LOS ANGELES— While one former "Mickey Mouse Club" star-turned-pop singer just shaved off her hair, another one has been trying different colors on hers.

In her upcoming "Candyman" video, Christina Aguilera rocks not just her usual blond locks, but also red and brunet ones.

"And for anybody who thinks that was digitally changed in some camera effect, it wasn't," Aguilera told MTV News. "That was me!"

In the clip, the singer plays three different versions of herself, each with their own personality.

"The brunette, she wanted to be a little naughty, that was my Xtina days," Aguilera explained, grinning. "She wanted to stir a little trouble. She was the third one to go up there, so I think she was a little tired and she was tired of seeing everybody get the limelight. The redhead, she's looking over at the blonde and she's got a little jealousy in her, like, 'Why aren't I singing the lead?' And the blonde is, of course, my side ... kinda sweet and sassy at the same time."

The three Christinas were a tribute to the Andrews Sisters, whose 1941 single "Boogie Woogie Bugle Boy" inspired "Candyman," which was the first song Aguilera and producer Linda Perry recorded for her '40s-influenced Back to Basics album (see "Christina Makes Her Comeback Twice As Nice By Expanding Basics Into Double LP").

"Linda was one of those people that completely went to bat, inventing it with me in an organic way," Aguilera said of her vision. "There was no beat machine, it was all live musicians and we just had so much fun creating and really diving into that world of creating music from scratch, which not a lot of people do anymore."

For the video, Aguilera teamed with Matthew Rolston, the photographer behind her recent Rolling Stone cover, as her co-director.

"We did kind of a takeoff of that Vargas-style pinup," Christina said, referring to famed pinup painter Alberto Vargas. "[We're] saluting WWII, the bomber planes, servicemen and all those things. ... It's a really strong visual for a video."

Aguilera learned the jitterbug for the video and then had to replicate her exact performance two more times so the three Christinas' choreography matched. "That was sort of painstakingly long to achieve ... but I know the outcome will be good," she said.

The "Candyman" video premieres Wednesday (February 21), one day after Aguilera's tour kicked off in Houston (see "Christina's Tour Takes Fans To Circus, Cabaret Club — And Church?") and 10 days after Aguilera's standing-ovation-inducing take on James Brown's "It's a Man's Man's Man's World" at the Grammys (see "Christina Talked Private Parts? Who Was Sick? Grammy Moments You Didn't See").

"I was studying James," Aguilera said of the performance. "I had bought the DVDs, I was buying the CDs, I had six different versions that I was listening to and taking notes from. So I definitely did my homework. And doing that scream [was challenging], 'cause I don't really screech."

Aguilera also won a Grammy for Best Female Pop Vocal Performance for "Ain't No Other Man" and was happy to see the Dixie Chicks so victorious (see "Timberlake Rocks; Blige Weeps; Chicks, Chilis Clean Up At Grammys").

"I think it's really great when you stand up for something that you really believe, even if you get heat for it," she said. "I'm no stranger to that."
