What’s up with Britney Spears?

In a somewhat cryptic new promo for this year’s MTV VMAs, Brit parties down while her new single “I Wanna Go” meets a mashup with “Slave 4 U,” Janet Jackson’s “Rhythm Nation” and Madonna’s “Everybody.” During a series of hyper-fast edits, a crowd of revelers dressed in some of Britney’s most famous stage costumes can be seen dancing around to the music medley.

The clip ends with Britney busting a move in front of a wall that reads “A Tribute to Britney Spears.” MTV’s site says to “stay tuned to see what it all means…”

In the meantime, they offer up some behind the scenes tidbits by talking to Brit herself.

“I did the opening segment, where I’m at the mirror and I’m representing how many albums I’ve done, which is number seven,” she says.  “I’m walking down a hallway and I’m seeing memorabilia of all my performances that I’ve done in the past … All my dancers are dressed up in my old outfits, which is really cool.”

Off screen, Britney was recently spotted with her longtime beau Jason Trawick while grabbing a sweet treat in Long Island. The two also took her kids out for a fun family boat ride!
