Has a misguided Tara Reid decided to fill the tiny, protruding rib cage-shaped void left by mommy-to-be Nicole Richie? The onetime party girl-turned-plastic surgery victim was snapped this week in Bali baring her bony body in a bikini while catching some rays, leading us to wonder whether she's swapped food for peroxide and self-tanner.

Alas, spindly limbs aren't the only things Tara's showing off these days.

She was also photographed with a sizable scrape on her elbow, the apparent result of a header she took while in Indonesia, where she's posing for an Australian pajama company (a major step up from her recent gig Down Under hosting the Hookers Ball, which was exactly what the title implies).

The New York Daily News reports the atrophied sometime-actress, 32, was treated at a local hospital for cuts and bruises after stumbling during a night out on the town, although her rep denies she received medical attention.

Her camp is also denying a Chicago Sun-Times report that says she'll soon check into rehab (come on, it beats the Hookers Ball).

So what's behind Reid's much-altered body, which has already endured a breast augmentation and liposuction (along with corrective procedures after both operations were reportedly botched)?

According to In Touch, it's a control issue.

"Tara kept turning to plastic surgery to fix her body," a "friend" tells the mag. "She was never pleased with the results, so she finally decided to take matters into her own hands."

Still, we're not entirely convinced the formerly pie-eyed host of "Taradise" has dropped an alleged 25 pounds off her already slender frame by sticking to a "strict, 1,200-calorie-a-day diet combined with 90-minute cardio workouts every day," as another pal claims.

"She clearly doesn't feel comfortable with herself," says a source. "She looks frighteningly thin."
