LOS ANGELES — Justin Timberlake is reuniting with his "Mickey Mouse Club" co-star.
No, not Britney Spears — Christina Aguilera.
At Monday's American Music Awards (see photos from the red carpet), Timberlake said his summer tour would be a co-headlining affair, but he stopped himself from divulging more. "I will not reveal the name and start some rumors," he said mysteriously.
Fortunately, Aguilera was just steps behind him on the red carpet and let the cat out of the bag.
"Oh my God! I'm so excited," Aguilera said. "Me and Justin are going to go out, and it's going to be such an amazing thing. There's talk of us writing a song together and what not. He's so great. We're going to make it the tour of the year."
Details on the tour are forthcoming. Meanwhile, Timberlake and Aguilera are preparing to release the third singles from their recent albums, Justified and Stripped.
Like his tour, Justin wanted to keep his song a secret. Christina is deciding between a few favorites.
"It could be 'Can't Hold Us Down,' which I did with [Lil'] Kim, or 'Fighter' is a big favorite with a lot of people," she said. "'Impossible' will be in the mix, and 'Infatuation.' There's so many that could be a possibility."
Aguilera performed "Impossible," which was written and produced by Alicia Keys, at Monday's ceremony, along with "Beautiful" featuring producer Linda Perry on piano (see "Missing Eminem Cleans Up At American Music Awards").
Before her summer tour, Christina hopes to choose a script to make her big-screen debut (see "Christina Aguilera Plans Tour, Movie Role For 2003"). "I definitely want to make a movie before my next album," she said Monday.
Timberlake said he'll do a promotional tour of Europe and hit the studio again before the tour with Aguilera. On Friday he shot a video for "Work It," his collaboration on Nelly's latest album (see "Nelly, Justin Bring Video Cameras To Playboy Mansion").
"Yeah, that was tough work," Timberlake joked. "I had to hang out with Hef, watch a bunch of naked women run around. It was awful."
