Tom is said to be particularly concerned that his glamorous actress wife has lost so much weight recently, and at the fact that Katie and Victoria appear to have morphed into each other.

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

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

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

Meanwhile Victoria is continuing her bid to win the hearts of the US public by focusing on her fashion career.

She is currently in talks to front a TV show called Fashion Nightmares, which will see her travelling around America doing style makeovers.

Victoria's denim range recently made headlines with reports that her line had been dumped by boutiques Kitson and Fred Segal from their stores because of poor sales.

Kitson owner Fraser Ross was reported to have said: "We asked her PR people so many times for her to appear but she didn't. Celebrity lines are no different from an album or music tour. They have to be promoted to sell."

However, the owner is now denying the reports.

He told British Vogue, "The rumours are ridiculous - Kitson is extremely proud to be selling dVb by Victoria Beckham. We are fully committed to the dVb collection and our customers and Victoria's fans ask for it daily."

"I've seen next season's collection and I can't wait to get it in-store, especially the new dVb men's collection launching in September."
