Nude sunbathing, garters, bustiers and waterbeds all seem to add up to trouble for actress Kristy Swanson.

The blond bombshell confesses to Maxim that she recently made the mistake of sunbathing nude on the balcony of her Miami hotel room while there to shoot CBS's now-canceled Grapevine. "I thought I was alone. But there were these big cranes on top of the hotel next door, and this one guy was up there, and he started waving at me. I was, like, 'Uh, tanning session over.' "

Swanson, who's probably best known for her starring role in 1992's big-screen version of Buffy, the Vampire Slayer, says she's actually had a number of embarrassing encounters with the opposite sex in her lifetime. A few years ago, for example, she made the mistake of trying to surprise her boyfriend by dressing up in a sexy outfit right out of a Victoria's Secret catalog.

"I put on stockings, garters, high heels and the whole bustier/bra thing," she says. "I thought it was cute and sexy. So I'm sitting there in a chair with candles lit and everything, and he walks in and laughs. I think he was just so shocked, he didn't know what to do."

Swanson also reveals her awkward first sexual encounter: "We didn't know what we were doing. And there was the possibility that his parents might walk in. And we were on a waterbed, which was a true test. Mostly I just remember it being over very quickly."
