When a girl's starting to doubt her sex appeal, after a foray into acting that has thus far earned her parts as a back brace-wearing nerd and the part of "Smoking Girl" in something called Whore, there is no better way to regain confidence and prove just how fine you are than nailing a gay actor (allegedly). And that's just the challenge Rumer Willis set up for herself during a recent night out. According to the NY Post, the rising starlet and failed auditonee of Lindsay Lohan's lesbian love lottery spotted boy band groupie Chace Crawford at a birthday party and tried every boy toy magnet trick she could think of in an extensively planned and bitterly fought campaign to pull off the rarely accomplished task of getting him to switch teams.

Though the Gossip Girl pretty boy has already doused gossip pages with gay rumours, Willis was allegedly gung-ho about grabbing the goldilock-ed birthday boy's attention. But instead of smartly following in his co-star Blake Lively's footsteps and donning a trustworthy bikini inspired by her own mother, Rumer thought a pair of her "shortest jean shorts" and impressive dance floor shenanigans would do the trick. Sadly, sources say Crawford was less interested in both her and Z-lister Brittny Gastineau's forays in conversion tactics: "He wouldn't give her the time of day." A sad moment indeed, but we do suggest Willis try her method out on Crawford's partner in fruitini-drinking crime JC Chasez, who, judging from our tipster's report months back, is much more interested in hiding his sexual preferences behind cabana doors.
