Pop Explosion: Madonna, JT, and Britney!

Ryan Seacrest reports on his website that Justin Timberlake and Britney Spears will reportedly join Madonna onstage tonight at Dodgers Stadium for her “Sticky & Sweet” Los Angeles show.

Try to breathe slowly, pop fans. In through your nose, out through your mouth. We have defibrillators on hand if need be. Ohmygosh, will Britney and Justin share the stage TOGETHER?!?!

“If Justin and Britney end up on that stage with her…I don’t know if I’ve ever seen anything quite like that before,” Ryan said on his radio show on 102.7 KIIS-FM in Los Angeles yesterday.

Britney Spears’ official site will reportedly confirm her appearance today.

Brit is actually already part of Madonna’s show. She appears in a video montage during Madonna’s performance of “Human Nature.”

And it’s almost definite that Justin will be there to duet on his hit single with Madge, “4 Minutes.”

Madonna could probably use some cheering up due to her divorce. What better way than to have two of her pop apprentices take the stage with her.

There’s also word that Alex Rodriguez is in Los Angeles. Front row seats for A-Rod?

It’s not Jerry Seinfeld’s mansion but it’s still a way to be in the same stadium room together.
