Beyonce and Jay Z try to keep their private life exactly that – private. But, the couple have been hit by more split allegations but this time it was over Rihanna.

In an explosive new claims, in a book by J Randy Taraborrelli titled Becoming Beyoncé: The Untold Story, it is alleged that RiRi was at the heart of affair rumours that saw Beyonce and the Hard Knock Life rapper split up.

The Drunk In Love stars, who married in 2008, rarely showed any form of PDA in public and tied the knot in secret, avoiding a media circus surrounding their nuptials with the couple only recently giving a glimpse inside their big day.

Without ever really lifting the lid on their relationship, the couple – who were recently dethroned as the highest paid couple by Calvin Harris and Taylor Swift – have been at the centre of sensational allegations and speculation ever since they first got together.

But is the Rihanna affair rumour the most shocking yet?

Beyonce’s ‘secret divorce plans’

Only a week after Beyonce’s 34th birthday, InTouch Magazine reported that they’re heading for a break-up.

“It’s dead,” an insider told In Touch. “Bey is sick of keeping up the ruse of happiness, and she’s done.”

The magazine claims that the couple have been in trouble since infamous footage of Beyonce’s sister Solange Knowles attacking her brother-in-law in an elevator after a 2014 Met Gala after party went viral.

“It’s like she’s on lockdown and doesn’t want to be asked about her marriage or why she and Jay haven’t had another child after Blue Ivy,” the insider reported.

“But in private, she’s already told friends and family that she’s moving forward with her life. She’ll soon make a public announcement that their marriage is over.”

Rihanna affair rumours rock Beyonce’s world

It’s now been claimed that Jay Z and Beyonce split for a year over rumours of an affair with Rihanna.

In an explosive new book that is set for release later this month, it’s claimed that the couple, who married in 2008, split up around the same time that Rihanna launched her debut single, Pon De Replay.

The rumours were allegedly started by publicists to put RiRi on the map and boost her profile, but Beyonce was not impressed and allegedly “wasn’t sure what to make of the situation”, the new book by J Randy Taraborrelli claims.

Of the alleged split, he said: “Beyoncé didn’t know what to make of this, and it actually ended up breaking them up for a time.”

Beyonce’s secret talks with childhood sweetheart

The couple began dating after meeting in 2001 at a 9/11 benefit concert, but during her 2002 Destiny’s Child world tour, Beyonce was on the brink of going back to her ex. Picking him over Jay Z.

In the new book by celeb journalist Taraborrelli, Beyonce reportedly continued to talk to her ex Lyndall Locke, even though her new boyfriend put his foot down.

Her ex said: “At one point she said, ‘I hate to tell you this, but Jay doesn’t want me speaking to you’.

“She talked to me anyway behind his back, and was just more discreet about it. I was too.”

Rita Ora rumours get people talking

Rita Ora has Jay Z to thank for her glittering career, and despite being married to Queen Bey, it didn’t take long for rumours to start about the two.

Just last year, Rita was still fending off questions about the outrageous rumours, lashing out at Power 105 FM’s, The Breakfast Club’s DJ

The DJ brought up the rumours, as he said: “Hold on, it was rumoured that you and Jay Z were boinking”

But the X Factor judge took no prisoners as she said: “Don’t you dare disrespect Beyonce like that ever again in your entire life”.

While he tried to justify the discussion by pointing out that it was a topic that Rita herself addressed on Twitter, she said: “Yeah cause that’s just straight up disrespect. You can’t even go there, that just not a question.”

Solange Knowles attacks Jay Z in the lift

In shocking footage that shattered the illusion of a perfect family unit, Beyonce’s younger sister Solange was seen ferociously attacking her brother-in-law Jay Z at a MET Gala after-party.

The trio were joined by security in a lift at the bash in New York, where Solange launched herself with kicks and punches at the 99 Problems rapper, while Beyonce remained weirdly calm.

They regained their composure as the lift doors opened and they got into their waiting cars, with Jay Z choosing to wait for a separate vehicle.

In a statement released on behalf of the family about the “unfortunate incident”, it read: “(T)he most important thing is that our family has worked through it.

“Jay and Solange each assume their share of responsibility for what has occurred. They both acknowledge their role in this private matter that has played out in the public. They both have apologized to each other and we have moved forward … At the end of the day, families have problems and we’re no different.”

In an interview after the incident, Solange told Lucky magazine: “What’s important is that my family and I are all good. What we had to say collectively was in the statement that we put out, and we all feel at peace with that.”

Why did Jay Z avoid his best friend’s wedding?

They were meant to be best friends, but Jay Z skipped Kanye West’s high profile wedding to Kim Kardashian as they kept a low profile following their elevator bust-up.

Despite the close relationship of the Watch The Throne stars, Jay Z was noticeably absent on Kanye’s big day in Florence.

Beyonce and Jay Z reportedly remained in the Hamptons , despite it being speculated that the hip hop star would perform best man duties.

At the time a source alleged that the couple avoided a run-in with Kim’s pal Rachel Roy, who was allegedly seen arguing with Solange because of her alleged relationship with Jay Z, according to Hollywood Life.

Rachel was previously married to Damon Dash, Jay Z’s former business partner.

It was also alleged that Beyonce didn’t want to be involved in the circus surrounding Kimye’s big day and didn’t want anything to do with reality TV.

While a rep for Kim dismissed rumours of a bust-up between Kim and Beyonce, they said: “There is no feud. It’s a tabloid fabrication.”

But a source told Woman’s Day: “Kim blames Beyoncé for Jay Z skipping their wedding.

“Kanye considered Jay family, and the last minute decision for him to not come to their wedding was extremely selfish.”

Caught fighting in public

Beyonce, who is usually the picture of composure, was seen rowing with her very famous partner in a rather public restaurant in February.

But while Queen Bey tried to get her point across, Jay Z couldn’t take his eyes of his phone, leading to speculation the couple were at loggerheads once again.

According to Grazia magazine, the mum-of-one was struggling with trust issues that aren’t helped by Jay always being on his phone.

A source said: “Beyonce seems convinced that Jay-Z is hiding things, and that there’s a huge amount going on that she isn’t privy to.

“He’s constantly on his phone and, when they’re at home, he’s lock away in his office for house on phone calls or on this computer, which are secured with passwords and access codes.”

Does Jay Z have a secret love child?

Blue Ivy might have a big brother, and Rymi Satterthwaite is determined to prove that the hip hop heavyweight is his daddy.

A New Jersey paternity suit was filed earlier this year demanding a DNA test to show whether he was the father of an aspiring rapper.

Satterthwaite claims his mother Wanda hooked up with Jay-Z in the early 1990s, according to the National Enquirer — long before the product of Brooklyn’s Marcy Houses became a multimillionaire recording star and music mogul.

It was not the first time that the allegation was raised, with New Jersey Superior Court Judge Edward McBride Jr. dismissing the case in 2010, according to the National Enquirer.

It was thrown out after a judge ruled that he lacked jurisdiction, with Jay Z’s lawyer successfully arguing that the superstar lived in Manhattan and not the Garden State.

Beyonce and Jay Z and THAT ‘fake baby bump’

While pregnant with their daughter Blue Ivy, Beyonce appeared on an Australian television show with Molly Meldrum and found herself at the centre of a ‘fake baby bump’ furore.

The Single Ladies, who was a first-time mum, was promoting her album 4 at the time, and as she went to take a seat for the interview while wearing a fuchsia dress, Beyonce’s crumpling of her dress appeared to show her bump being squished as she took a seat.

At the time a representative for Beyonce told ABC News that the rumours were “stupid, ridiculous and false”.

She addressed the continued speculation in person while speaking with Katie Couric for ABC’s 20/20.

“You know there are certain things that are so far, it doesn’t even affect me,” she said.

“I am cool, it is so ridiculous and over the top.”
