Britney Spears 'Wants to Eat Like Victoria Beckham'

Britney Spears is so determined to lose weight -- she taken to copying Victoria Beckham's fat-free diet.

The 'Toxic' singer, known for her love of Starbucks coffee and Red Bull, is embarking on a super-healthy diet plan of steamed fish and vegetables -- just like the former Spice Girl.

A source close to the singer reveals to Britain's New! magazine, "She's been eating steamed fish and edamame beans.

"She was told that's what how Victoria stays so slim. She's also drinking goji berry juice and seaweed shakes to stave off hunger and starts each day with a cup of hot water and lemon."

The singer's new diet plan, which is monitored by her father Jamie, a trained chef, has seen Britney drop from a dress size 14 to a size 10.
