If you watched the 2012 MTV Video Music Awards earlier this month, chances are you caught Rihanna's opening performance. And at one point, she went right into the remix of "Cockiness," which features guest vocals from A$AP Rocky. He would eventually hit the stage, spit his rhymes, and as you can see above, grab RiRi's butt.

But (no pun) it wasn't a planned move for Harlem-repping MC. As he tells V103, "It just happened."

“It really wasn’t no idea ... I thought it was just one of those moments,” he said. “I didn’t know everyone was really talking about it.”
