Tom Cruise is said to be scared that disappearing Katie Holmes is slowly morphing into her bony pal, Victoria Beckham.

According to a new report, the actor feels that the former Spice Girl is a bad influence on his wife, whose weight has plummeted in recent months.

"Katie sees Victoria as a role model," a source tells The Daily Mail. "She copies Victoria's look and even cut her hair the same way.

"She is very thin largely because she is following Victoria's strict 900-calories-a-day eating plan.

"She is copying Victoria's fad of eating seaweed shakes, frozen grapes and edamame beans. She is tiny."

Who do you think Katie should have as her role model instead? Be sure to let us know.
