Katie's Holmes Starving!

No wonder Katie Holmes had to take a break from her new best friend, Victoria Beckham - she was starving. The super-skinny soccer wife had been helping Holmes lose her baby weight, but it seems Beckham's dietary rules were too much. A spy said, "Victoria maintains her tiny frame because she only permits herself to snack - not eat - on edamame, pretzels and occasionally sushi." Beckham also is a Diet Coke fanatic and told pals she hasn't drunk water in years because she "hates the taste."
