Posh Diet Too Tough For Katie Holmes

Victoria Beckham had been helping Katie Holmes lose her baby weight in preparation for this week’s big wedding to Tom Cruise, but the former Spice Girl’s dietary rules were apparently too much for the actress. “Victoria maintains her tiny frame because she only permits herself to snack – not eat – on edamame, pretzels and occasionally sushi,” a source told The New York Post. Posh also is a Diet Coke fanatic and told pals she hasn’t drunk water in years because she “hates the taste.”
