Flash back to 2003's MTV Video Music Awards: Madonna orchestrated the night's most-talked about moment by kissing both Britney Spears and Christina Aguilera onstage during a medley of the pop queen's songs including "Like a Virgin."

It was a symbolic passing of the pop-star torch, and it made headlines for days, cementing Madonna's relevance amongst younger, radio-friendly competition like Spears and Aguilera, who were then dominating the music charts.

Nine years after that kiss seen 'round the world, Madonna could very well be gathering the former Mickey Mouse Club co-stars together for a reunion of sorts. According to the Twitter feed for the singer's latest album, MDMA, Aguilera will appear at Madonna's concerts in Los Angeles on Oct. 10 and 11 for a "special performance," while Spears will "attend" the show on the 10th.

Reps for Madonna and Spears did not immediately comment on what Spears' appearance might entail, and whether she'd jump on stage with Aguilera.

Meanwhile, Spears is preparing to make her official debut as a judge on The X Factor alongside Simon Cowell, L.A. Reid and Demi Lovato. The second season of Cowell's revamped series premieres Sept. 12. The same week, on Sept. 10, Aguilera will reprise her role as a mentor on NBC's hit singing competition The Voice. (Cue the old Britney-versus-Xtina chatter.)

As for Madonna, she's wrapped up her MDNA concerts in Europe by sending olive branches to Elton John and a French right-wing politician, and joining the chorus of protesters urging Russia to free Pussy Riot. She launches the North American leg of her tour on Tuesday in Philadelphia.
