Ew, ew, ew, ew, ew!

Lots of disgusting PDA stories from our favorite (or perhaps, least favorite) teen stars ...

As Bruce Willis prepares to turn 50 later this month, the actor enjoyed a mutual gropefest with 18-year-old Lindsay Lohan after the premiere of his new flick 'Hostage' at Peninsula Hotel. "At one point, Bruce had Lindsay's pants down far enough to reveal a tattoo that said 'La Bella Vista' (The Beautiful View) on her right cheek," a witness revealed. Eventually, Willis and a few friends, including Lohan, took the party upstairs to his suite.

Star magazine reports that Hilary Duff and sister Haylie Duff were doing some canoodling with their boyfriends at Hollywood's Club Xes for Haylie's 20th birthday bash. Underaged Hilary was "holding hands, snuggling and kissing up a storm all night long" with her 25-year-old Good Charlot[t]e beau Joel Madden, while Halie and her guy Erik von Detten were spotted "kissing in the corner."
