Sorry Posh, Tom's already got the role

But it seems she borrowed her latest sartorial statement from the husband of one of her best friends.

The Spice Girl raised even more eyebrows than usual when she left Los Angeles airport dressed in a military-style jacket and peaked cap.

The outfit bears more than a passing resemblance to the on-set costume worn by Tom Cruise in his new film Valkyrie.

Victoria Beckham's military-style jacket and peaked cap bears more than a passing resemblance to the on-set costume worn by Tom Cruise in his new film Valkyrie

Cruise - husband of one of Mrs Beckham's closest showbiz friends, Katie Holmes - adopted the look for his role as Hitler's failed assassin Colonel Claus Schenk Graf von Stauffenberg.

Both outfits included tight-fitting grey tailored jackets cinched at the waist with a distinctive belt, finished off with business-like leather bags.

For Posh, the clothes were designed to get attention at a time when her profile is in decline. After arriving in California amid a storm of publicity, her hoped-for career in Hollywood has yet to materialise.

A source close to Victoria said: "Things are not really going as she had planned.

"Victoria has a small cameo in Ugly Betty.

"She wanted a much bigger role in that - and indeed a lead role in any show at all.

"Katie Holmes had been helping her with scripts and perfecting her acting but even that has not helped the situation.

"Victoria had hoped to be picking and choosing presenting roles too. She had wanted perhaps to guest host on Larry King - in the way that Heather Mills did. But that has not worked out either.

"She had been hoping that the documentary about the Beckhams moving to America would be made into a series, but it was cut right back too.

"Victoria had also set her sights on getting the cover of American Vogue but that too has proved elusive. Basically she pinned her hopes on offers of work coming flooding in but that just has not happened."

Meanwhile New York trend magazine, Radar, voted Mr and Mrs Beckham number 1 in the Overrated Top 100 last week.

The survey concluded: "He's an overpaid soccer star; she's a pointless collection of body parts."
