This pop star is certainly hands on with herself!
While performing last night in L.A., the sexy singer couldn't resist grabbing a handful of her own booty.
Then again, considering some of her recent racy music videos, you could almost call this tame...for her.
Think you know who's getting cheeky? Find out after the jump...
It's Rihanna, who took over the Staples Center last night for her Loud tour.
Jamie Foxx was in the audience to witness Ri-Ri's show, but one celebrity wasn't even able to score tickets herself.
Birthday girl Khlo Kardashian Odom took to her Twitter to complain : "I was so annoyed that I couldn't go to @ rihanna concert tonight. But I am working on tickets for tomorrow night! Thank you for multiple tour."
Rihanna seemed pleased with her performance last night, judging by her postshow celebrating.
"I swear to Drunk, I'm not GOD!!!" she wrote around 2 a.m.
She's been having quite the wild week.
"I officially lost my liver last night!!!" she tweeted Monday about her Sunday night partying, where she supposedly attended the same BET Awards afterparty as her ex Chris Brown. "Apparently I also molested 2 girls in the club!Whoever u are...ladies I thank u! U made my night way 2 much fun! Atleast that's what I heard."
