Nicki Minaj is known for her bodacious booty — even showing it off in her "Anaconda" video! — but we were still shocked to see a fan openly grope the singer's bottom onstage.

In a TMZ video, you can see exactly what went down. During a recent show in Germany, Nicki brought a fan up onstage. The fan seemed understandably excited to speak with the rapper and got a little too enthusiastic when Nicki began to perform.

As the fan sits in a chair, Nicki dances next to her and is shockingly unfazed when the fan's hands slip from her waist to her butt. Even more surprising, Nicki responded by fondling the fan's breast. Onstage. In front of a crowd of people. Yep, that happened.

And it appears that Nicki wasn't just playing along for the crowd. She posted an Instagram photo of the incident, along with the caption, "She wanted to get it poppin so I got it poppin right back. I'm not kidding. Tittieez on fleek."

The Frankfurt show was a stop on the European leg of Nicki's 2015 Pinkprint tour. 2015 is ramping for the singer. She made headlines after an awkward moment on the Grammys red carpet. Nicki also lent her mad rapping skills to a remix of Maroon 5's "Sugar." And in case watching the singer's butt being fondled onstage isn't up-close-and-personal enough for you, you can check out her new documentary My Time Again, which aired on MTV back in January.
