Stars Converge Upon Madonna’s L.A. Concert

Not only were Los Angeles concertgoers treated to the pop trifecta of Britney Spears and Justin Timberlake joining Madonna on stage last night at Dodger Stadium, there was a speckling of stars in the audience, too.

Hayden Panettiere brought some of her pals to the show, though supposed boyfriend Milo Ventimiglia was nowhere to be seen.

Maybe he was off lurking in the shadows, making sure his girlfriend didn’t sneak backstage for any shenanigans?

Also at the gig were Ryan Seacrest, Amanda Bynes and Jennifer Lopez.

Lisa Rinna strolled in on her own pace. But not before giving some lip to an Entertainment Tonight reporter.
