WASHINGTON, Sept. 4 ?  Britney Spears can get a lot of mileage from a kiss. The pop star said during a news conference promoting Thursday night?s NFL kickoff celebration that her attention-grabbing smooch with Madonna at last week?s MTV Music Awards was the first time she?s ever kissed a woman.

SPEARS SAID THAT she and the pop diva hadn?t practiced the kiss during rehearsal but that Madonna had told her they would ?just feel it out and see what happens? during the performance, according to CNN.
       ?I didn?t know it was going to be that long and everything,? Spears told CNN. ?I never kissed a woman before.?
       Spears said she left the United States for England immediately after the Aug. 28 awards show and was unaware of all the media attention the kiss received.
       Would she do it again?
       ?No, I would not do it,? but then added, ?Maybe with Madonna.?
       When asked if her clean Mouseketeers image had been changed by the kiss Spears told CNN, ?I think I?m still clean living. I mean I don?t go home and have orgies or anything like that.?
       Spears also told CNN that she would like to live in London, where her idol Madonna now resides.  
         ?It?s the one place that I feel completely anonymous. And I just like the way they treasure everything. Everything is very simply done,? Spears said. ?The milkman still comes to the door. I like the simplicity of that.?
       Spears will headline the NFL season-opening event on Thursday night, along with Aerosmith, Mary J. Blige, Good Charlotte and Aretha Franklin.

Madonna has agreed to star as a kinky leather-clad dominatrix in Britney Spears new music video. The pop queen will also lend Britney her husband, Guy Ritchie, who will direct the promo for her new single "Me Against The Music," on which Madonna collaborated. In the video, the Material Girl will play a scary nightclub owner, with a string of luscious ladies on leashes, who lures innocent scantily-clad Britney into a private room filled with other beauties. The saucy video will echo Madonna\'s controversial MTV Video Music Awards performance, where she passionately kissed both Britney and Christina Aguilera. Madonna and Snatch helmer Guy last worked together on the flop film Swept Away.
