If The Ugly Truth hits it big at the box office this weekend, be prepared for a nationwide shortage of vibrating panties.
In the romantic comedy, Katherine Heigl plays Abby, a buttoned-up television producer who spars with a chauvinistic TV commentator played by Gerard Butler. In one scene, Abby accidentally finds herself being sexually satisfied by a pair of remote-control lacy underwear...during a business dinner in a restaurant!
While Heigl's work may not be up there with Meg Ryan's iconic pseudoclimax in When Harry Met Sally, she bravely shows no restraint in her moaning, groaning and body-trembling performance.
With that in mind, we thought we'd hit up some sexperts to get the inside scoop on the adult-only knickers, plus we find out which real-life celebs already own a pair or two…
"It's a fun secret that people don't talk about," says Kristen Tribby, education and marketing director of L.A.'s celebrity sex shop, Pleasure Chest. "They are good for things like boring holiday parties. It's a great thing for a couple in a playful spirit. It gives them a way to be exhibitionists, but in a discreet manner."
But you probably shouldn't take a cue from Heigl on locale. A quiet restaurant isn't the ideal place for public playtime, because they make too much noise. Instead, hit a nightclub. "The remote works form 35-40 feet away," says Jacqueline Deidun, manager of Lover's Lane, a boutique in Sterling Heights, Mich. "You can be on the dance floor and your man can be at the bar."
As for celebrity couples who already own a pair, Dana B. Myers of L.A.-based adult toy and accessories company Booty Parlor says she's provided panties for Tori Spelling and Dean McDermott along with E! reality star newlyweds Kendra Wilkinson and Hank Baskett.
So the next time you see them on the red carpet, it may not be their BlackBerry that's doing all that vibrating.

Tomorrow: Come back here to find out what the friggin' deliciously hot-bodied Eric Winter, who plays Heigl's next-door-neighbor love interest in the flick, has to say about sitting right next to her during the climactic scene.
