Britney Spears: Liposuction Fiend?

Plenty of us lose money in Las Vegas.

Britney Spears apparently loses weight.

And her mind, possibly. Though that's been MIA for months now, so we can hardly blame her possible insanity on the effects of Sin City.

With Britney Spears' penchant for almost invisible dresses - and photographers' penchant for Britney Spears - it's been hard to miss her noticeably leaner post-rehab figure.

The troubled pop star has dropped 12 pounds, to be exact, a fact which Brit's new trainer, Manny Bujold, calls the result of "more squats and fewer Cheetos."

She even pops a squat while shopping at Target.

"She works extremely hard," Bujold said.

However, rumors are swirling that 25-year-old mother of Jayden James might be cheating in her weight loss campaign. We're talkin' Star Jones style.

Britney Spears, who may or many not have fired manager Larry Rudolph, was seen at a LipoDissolve clinic in Las Vegas on March 31, leading people to wonder if she gave her weight loss efforts a shot in the arm, so to speak.

It's a series of shots that literally melt away extra pounds. Oh well, at least her boobs are real.

This wouldn't be the first time Cue Ball had a cosmetic trick or several up her sleeve (or under her lovely wig).

Just a few days prior to her LipoDissolve mission, Britney also visited a celebrity dentist to erase all traces of Red Bull, cigarettes, booze and soft drinks from her choppers with the Zoom laser whitening treatment.

If only a doctor could make those ridiculous hats disappear. Or those cowboy boots. Oh well, at least she's decided it's okay to wear panties.
