Mike "The Situation" Sorrentino feels bad he mocked his Jersey Shore costar Nicole "Snooki" Polizzi's "rolls" on last week's episode.
"I regret saying it because I have a sister and a mother, but at the same time, everything happened so quickly and that is what happened," The Situation, 27, told UsMagazine.com at the GBK Gift Lounge in West Hollywood Friday.

The Situation explains that tension had been building up -- and came to a head while the cast was having dinner in Atlantic City together.
"We were getting on each other's nerves," he says. "It just so happened that previously Snooki had said something to me and I immediately said something to her."
On the show, Snooki, 21, stormed out of dinner and admitted she'd battled an eating disorder. But she has since said she has no hard feelings -- and even occasionally "hooks up" with The Situation.

"It's not awkward at all," Snooki told E!'s Chelsea Handler. "If I wanna make out with him right now, I can. It's not weird."
The Situation also opened up to Us about all the star attention he's been receiving since appearing on the MTV hit -- like hanging out with Leonardo DiCaprio at Hollywood hotspot Voyeur last week.
"Leo recited one of my lines from my show and that was so awesome," he said. "Everything is going so fast right now and we are meeting so many different people. I am shaking every hand and kissing every cheek, I am just being respectful."
