As rumored, both Britney Spears and Justin Timberlake joined Madonna onstage last night during the Material Girl's Sticky & Sweet stop at Dodger Stadium in Los Angeles. During "Human Nature," the third song of the evening, Madonna handled the bulk of the Bedtime Stories track while the video of Spears freaking out in an elevator played in the background as usual. During the final chorus, Spears finally emerged, sharing the singing duties with Madonna before being lowered into center stage to make her grand exit. Shaky YouTube footage of the performance can be seen here. Justin Timberlake also showed up later in the night, joining Madonna as he often does for Hard Candy's "4 Minutes." Check the video here. Rumors abound that Brit might show up again during Madonna's Las Vegas shows this weekend, but nothing's been confirmed as of yet. Spears' new album, Circus, is due December 2nd.
