BRITNEY IS NOT INTO POSH

Britney Spears has plenty to worry about -- kids in limbo, career in the crapper, terrible hair -- but she's apparently still got room to bitch about having to sit near Victoria Beckham at the Chateau Marmont.Gatecrasher reports that Brit-Brit showed up at the Chateau last week, but -- horrors! -- the "only table available was the one next to Posh." Britney couldn't deal with sitting next to the arriviste Becks, so she high-tailed it to Il Sole instead.
