Stepping out for an evening on the town, a glammed up Victoria Beckham was spotted visiting Eva Longoria's restaurant "Beso" in Los Angeles on Tuesday night (November 18).

The former "Spice Girl" donned a snug white corset dress, which showed off what's becoming a more and more petite frame in recent weeks.

Sources claim that the weight loss is tied to her "panic mode" over husband David Beckham's upcoming move to Italy to play a season for AC Milan.

"She's losing weight because of the stress of him moving away and the next few months will be tough on both of them," an insider told Grazia magazine.

"When they first talked about him going, I don't think she thought twice about it. But now that it's been announced and everyone has had their say, it's become upsetting," the source adds.

"Victoria seemed stunned that people have suggested David might be off as soon as he got the opportunity. Any woman would feel paranoid with all that speculation. It's gutting for her that people would think that."
