Say this for Britney Spears: she’s loyal. The pop princess tells CNN’s “Crossfire” that she would kiss no other woman but Madonna — whom she also says is the first woman she’s ever kissed.

For those who might have been embedded in a Tibetan monastery last week, Madonna, 45, and Spears, 21, lip-locked for a prolonged, open-mouth kiss at Thursday’s MTV Video Music Awards. (Madonna also kissed Christina Aguilera.)

“I didn’t know it was going to be that long and everything,” Spears told CNN (which, like PEOPLE, is part of AOL Time Warner.)

She said the gesture grew out of rehearsals and that Madonna suggested they “just feel it out and see what happens” during the show.

“I’ve never kissed a woman before,” Spears said in a manner described as demure.

And would she do it again? “No, I would not do it,” she reportedly squealed before adding, “Maybe with Madonna.”

Asked whether the nationally televised kiss might have tarnished her once squeaky-clean Mouseketeer image, Spears replied, “I think I’m still clean living. I mean I don’t go home and have orgies or anything like that.”

She said Thursday’s kiss was simply a way of “performing and expressing myself.”

On a political note, Spears also confided that she supports President Bush and doesn’t care for celebrities who criticize the war on Iraq, saying: “Honestly, I think we should just trust our president in every decision that he makes, and we should just support that and be faithful in what happens.”
