Britney Spears is ‘not sorry’ after Justin Timberlake’s rumored shade: ‘Someone is talking s—t’

Things are getting quite toxic.

Pop diva Britney Spears posted a cryptic photo on Instagram Thursday in which the riled-up singer claimed someone was “talking s–t” about her.

“Someone told me someone was talking s–t about me on the streets,” Spears, 42, captioned a photo of a basketball hoop with the the moon behind it. “Do you want to bring it to the court or will you go home crying to your mom like you did last time???”

“I’m not sorry!!!” the post concluded.

The Post has reached out to Spears for comment.

Spears’ scathing and vague post comes a day after ex-boyfriend Justin Timberlake made an equally vague statement during a show in New York on his 43rd birthday.

“I’d like to take this opportunity to apologize to absolutely f–king nobody,” Timberlake told the crowd as the band played the melody of his 2013 Jay-Z collaboration “Holy Grail.”

Fans have deduced that the “Mirror” singer was referring to a statement made by Spears, whom he dated from 1999 to 2002, in which she offered an apology to him on Instagram. The post has since been deleted.

“I wanna apologize for some of the things I wrote about in my book. If I offended any of the people I genuinely care about, I am deeply sorry,” Spears captioned an Instagram post of Timberlake on “The Tonight Show Starring Jimmy Fallon.”

The Princess of Pop also stated that she was “in love” with Timberlake’s new track, “Selfish.”

“It is soo good and how come every time I see Justin and Jimmy together I laugh so hard,” she gushed.
