Britney Spears, Justin Timberlake Join Madonna On Stage In LA

As expected, Madonna brought out the big guns for her concert at Los Angeles’ Dodger Stadium on Thursday night, as Britney Spears and Justin Timberlake joined the Material Girl on stage, although at different times.

Wearing a subtle white blouse and black baggy pants, Britney joined Madonna on stage to sing the last verse of the track “Human Nature,” much to the delight of the packed house, which included some serious star power, including Jennifer Lopez, Ryan Seacrest, Heidi Klum, Drew Barrymore, Nicole Richie, Fergie and Donald Sutherland.

At the end of the song, Madonna then proclaimed “I’m not your b***h!” She then pointed to Britney, adding “She’s not your b***h,” drawing raucous applause from the crowd.

“The crowd went insane,” a concertgoer told Access Hollywood.

The superstar collaboration also included a kiss – although much tamer than the pair’s infamous MTV VMA liplock in 2003.

As Brit finished up her performance, Madonna gave her a hug and kissed her on the hand as Britney left the stage.

Near the end of the show, Justin Timberlake got the crowd buzzing as he took his turn on stage with Madonna, appearing to duet on the hit “4 Minutes,” the same song the pair teamed up for on Madonna’s “Hard Candy” album.

During the concert, Madonna also took the opportunity to offer a bit of political insight, in light of the controversy surrounding California’s Proposition 8, which was passed this week.

“If we can elect an African American as president, we can support gay marriage! Defeat Prop 8! We will not give up!” she told the audience.
