Oh yeah, Posh Spice needs to be a little slimmer. Uh huh.
Last week's "Welcome to L.A." party for Becks and Posh featured Fuze's Slenderize drink -- in six fruit flavors that have five to ten calories per serving -- and already slim stars like pop blonde Jessica Simpson and tiny-waisted teen Hayden Panettiere are downing the diet beverage by the case.
Robowife Katie Holmes requested the low-carb drink be available at the party -- though, really, do these svelte celebs need to be any skinnier?!
