Apparently, Stacy Keibler just wants to have fun.

The former wrestler, who is dating one of Hollywood's hottest bachelors, is a "blast to be around," her ex, Geoff Stults, tells PEOPLE. "She would be everybody's best friend," the actor, who dated Keibler for five years before the couple split in early 2010, said Sunday after finishing the Nautica Malibu Triathlon. "She's the kind of girl that people want to hang out with."
 And that includes George Clooney, who was recently spotted with Keibler at the Toronto International Film Festival. 

So what kind of boyfriend does fun-loving Keibler want to hang out with?

"I think just a good sense of humor," she told PEOPLE Monday at the Appleton Estate Reserve "Remixology" bartender challenge in New York. "And polite ... I think someone who is genuine and honest and someone who likes to have a great time no matter what they're doing."

Keibler was just "living in the moment" when she and Clooney began their relationship. "I was actually not really searching for a boyfriend," she says.

And now that the pair are an item, it seems she's not worrying too much about what the future holds.

"I don't think about that. I live in the present moment," she says. "That was my New Year's resolution ... and it's worked out pretty good so far.
