It’s arguably her most famous asset, so it’s no wonder a female fan grabbed some of Nicki Minaj’s derriere when she got the chance to onstage.

The lucky lady was invited up to join Nicki during a show in Frankfurt, Germany over the weekend and didn’t waste any time grabbing the rapper’s behind.

Laughing it off, Minaj squeezed the fan’s bust in return as male dancers gyrated around them.

Following the show, Nicki tweeted, ‘She wanted to get it poppin so I got it poppin right back. I’m not kidding. Tittieez on fleek (sic)’.

Nicki, who coined the term ‘pretty on fleek’ thanks to a recent collaboration with Beyoncé called Feeling Myself, has been a driving force in changing the world’s perception of beauty and helped bring much more curvaceous women to the spotlight.

Explaining how she used Anaconda, which was the second release from her latest album The Pinkprint, as a way to encourage voluptuous females to be proud of their figures.

She asserted to MailOnline: ‘When I set out to do Anaconda I definitely wanted something that was going to give girls permission to be curvy or be thick.

‘I felt like we had come to a place where we were all worshipping the skinny girls, and I I think that we always need to be reminded there are lots of different kinds of girls out there and they need to feel like we represent them too.’

Admitting that she prides herself on being multifaceted, Nicki revealed that her upcoming tour will blow her fans away as it is set to be her most ‘truthful and honest’ show to date.

‘It’s very rare that I just get to be on stage and speak from my heart to people who know me’, she said about The Pinkprint Tour, which kicked off in Stockholm on March 16 and arrives at London’s O2 Arena on March 28.

On Tuesday last week, she announced a summer of arena shows in North America following concerts in Europe despite the killing of her tour manager.

Minaj, one of the most successful female rappers, announced 14 shows in the United States and five in Canada starting on July 17 in Dallas.

The Pinkprint tour went ahead even though Minaj’s tour manager, De’Von Pickett, was stabbed to death last month outside a bar in Philadelphia.
