The last time Britney Spears and Madonna shared a stage together (at the 2003 MTV Video Music Awards) they nearly set the place on fire with their steamy on-stage kiss. Several kids, a divorce and plenty of drama later, the Queen of Pop and its forming reigning Princess just may get together again for Madonna's Sticky & Sweet tour, which starts next month, an insider told E! News. "[Britney] is considering doing a video piece for Madonna's tour," the insider tells E! News. The video would be shown on giant screens on-stage, but don't expect a real live appearance from Brit. The insider says reports that Madonna invited Britney to perform with her are "wrong."
