*First Rihanna, now Regis.

What is it about Nicki Minaj that makes people actually act on an impulse to touch her inappropriately?

Days after Rihanna grabbed her around the butt pads while hugging her in concert, the rapper was not only stroked by Regis Philbin following her performance of “Right Through Me” on Monday’s “Live with Regis and Kelly,” but he patted her butt as well, leaving Kelly Ripa and the audience in shock.

“Regis! What just happened?” said Kelly, seemingly appalled.

Afterward, Minaj tweeted that she was also taken aback.

“LOL. I was in shock!” she tweeted in response to a follower that asked her, “What went thru your mind when Regis had slapped ya? That was epic!”

In addition to getting handsy with the rap star, Regis also flirted verbally after Minaj told Philbin of the advice she got from her friend Lil Wayne.  “Wayne tells me to go hard,” said Minaj.

“Go hard?” asks Philbin. “I wish I could.”
