Madonna and Britney may replay The Kiss - knees permitting

Madonna has invited Britney Spears to perform during her first New York show on Wed night, causing speculation the duo plan to recreate that controversial kiss that occurred at the MTV Music Awards last August. A source in the Britney camp has told the Sun: "Britney was delighted when Madonna asked her if she could join her on stage. They got loads of reaction the first time they kissed. She agreed to do it immediately. Their people have been faxing and e-mailing non-stop to sort things out. Everything was confirmed last week." However it is not clear whether Britney will be able to make the gig at all after undergoing surgery on her knee after falling at a video shoot last week.
