So the rumors of a Madonna-orchestrated Britney and Justin reunion were true… kinda.  The former teen sweethearts both performed with the Material Girl during her Thursday night concert in L.A.’s Dodger Stadium, but not together.

In fact, there was at least an hour between their respective appearances, so it’s anybody’s guess whether they even ran into each other backstage.

Brit was first to emerge, joining Madonna early in the night to sing the the last few bars of “Human Nature.” The two women embraced at the end of the performance to wild screams from the crowd, at which point Britney promptly marched offstage. Truth be told, Britney’s performance was so short that if you had blinked you might have missed it.

JT, on the other hand, at least hung out for an entire song. He joined Madonna for “4 Minutes,” a song from her latest album that he co-wrote and produced.

Both Britney and Justin elicited big roars from the audience, but the biggest screams of the night came when the massive screens at the back of the stage flashed images of President-elect Barack Obama. Madonna told the audience that Obama’s victory was a big reason to celebrate, but she also expressed her disappointment that California voters, at the same time, had approved a ban on same-sex marriages.

“If we got an African American in the White House, then we can have gay marriages,” Madonna told the crowd.
