LONDON, UK  [Friday Nov.7.2003]  /Mix103FM.com/ -- If you can believe what you read on websites, the former collaborators on "Lady Marmalade" are at each other's throats: Christina Aguilera and Pink are on the outs, with both dis-inviting the other to each one's parties.

It happened in London, where stars were holding private parties: Aguilera's for her current tour, and Pink's for her new album. TeenHollywood.com reports that after being stiffed at the door at Christina's after-show party, Pink hightailed it to her own, leaving instructions that Aguilera was to be turned away.

No word if Christina actually tried to crash the party in pink.
