Olivia’s Wilde's On-Screen Lover Says She Has Potty Mouth

Olivia Wilde is the world’s hottest property since scoring the coveted top spot on Maxim’s Hot 100 list for 2009, but according to her “House” lover Omar Epps, the 25-year-old has a less-than-attractive mouth.

“She is a great girl and she is great to work with. But she curses,” Epps told Tarts recently. “Alot.”

The hit show’s producer David Shore concurs.

“We all really enjoyed the fact she was on the cover Maxim, but we’re used to Olivia’s hotness,” he said. “But she does curse a lot. She grew up in a barn I think.”

So what are Ms. Wilde’s tips to uber-hotness?

“Water, I always figure I always eat whatever the hell I want, but only if I'm drinking tons of water,” she told Tarts (and note the curse word already in her first sentence) at the recent EXPRESS TXT L8TR Campaign Event at Nobu West Hollywood. “If I miss lunch, I'm dangerous. I also love avocados. I feel like I always have avocados at my house. For me, they're nature's gift. I do enjoy exercise, but I’m not a very disciplined person. I like spinning, which is kind of embarrassing.”

And even though the strict vegetarian (whose guiltiest pleasure is dark chocolate) pretty much has the ultimate flawless figure, Wilde said sometimes showing it off is tough.

“I just did this big action movie, and I had to fit a tight little rubber cat suit, and for that I had to force myself to be careful at times,” she added. “But once I was in the suit I was like, it stretches! I'm cool.”

Kim and Reggie Reunite?

Despite murmurs of wandering ways for both parties, it seems Kim Kardashian and her ex-boyfriend Reggie Bush may very well be rekindling their romance. According to a close inside source, the reality starlet flew to New Orleans over the weekend to spend some quality time with the NFL player and “talk things through.”

“They both still have very strong feelings for each other,” a pal told us. “I’m sure they’ll work it out.”

Speaking of the Kardashian’s and rocky relationships, sisters Kourtney and Khloe Kardashian celebrated the launch of their new E! reality show, “Kourtney and Khloe Take Miami” with a Sin City pool party at MGM’s WET REPUBLIC on Sunday afternoon. Although five months pregnant, petite Kourtney was barely showing. Someone else who wasn't showing at all? Her baby daddy/ on-again, off-again boyfriend Scott Disick.

Mind you, Disick was spotted partying at WET REPUBLIC just the day before, but was a no-show for Kourtney’s poolside appearance. We're told that the two are together, however, as a result of Disick's wandering ways, he's been placed under strict orders to always be on his best behavior.
