Somewhat lost in last week's announcement that both [article id="1646546"]Usher and Paramore will be performing at the 2010 MTV Video Music Awards[/article] was the news of who else would be joining the festivities ... and no, we're not talking about the stars of "The Social Network."

It's Robyn, the Swedish superstar who, slowly but surely, has begun her stateside assault with a pair of highly touted pop albums (Body Talk Part 1 and Body Talk Part 2, both released this year, with a third installment due in December), a stirring single and video ("Hang With Me"), and a string of sweat-drenched, sweet-and-salty live shows. And on VMA night, she'll take another step toward mainstream success when she performs with [article id="1645817"]house artist Deadmau5[/article] during the big show.

She's just one of the artists who'll be jamming with Deadmau5 -- other confirmed acts include Travie McCoy and Jason Derülo -- but she's certainly the one with the most to prove. After all, to most VMA viewers, she'll be the wild card, the great unknown. And, as she told MTV News, Robyn is more than honored to be performing ... and definitely looking forward to the challenge.

"Deadmau5 is fantastic and I'm super-duper excited to be able to perform for the VMA audience," she said in an e-mail. "I'm gonna be 'dancing on my own'!"

That, of course, is a reference to a (really awesome) single from the first Body Talk album -- she'll be performing "a never-before-heard mix" of it at the VMAs -- and though you probably aren't familiar just yet, we're willing to bet that after Robyn rocks the show, that will change. Quickly.

The 27th annual MTV Video Music Awards will be broadcast live from the Nokia Theatre in Los Angeles on Sunday, September 12, at 9 p.m. ET.
