Florence And The Machine To Perform At Video Music Awards

Their 'Dog Days Are Over' clip is nominated for four VMAs at the September 12 show.

She surprised pretty much everybody when her video for "Dog Days Are Over" racked up four nominations at the 2010 MTV Video Music Awards, and now, flame-haired siren Florence Welch (and, of course, the Machine too) have been tapped to perform the song on the big show, which airs September 12 at 9 p.m. ET.

And yes, they'll be aiming to surprise once again. Though, as Welch told MTV News last week, after learning of her noms, the celebs in the audience probably won't be the only ones who can't believe what they're seeing.

"I'm still kind of processing it, to be honest," Welch said. "It's such an iconic event, and it's something I've watched on TV since I was a kid. It's one of those things: It's not real life, it's a dream scenario. So for me to be actually a part of it feels like I'm in some sort of parallel universe. It's kind of strange and wonderful and terrifying all at the same time."

And that's a pretty good way to describe everything Florence and the Machine do (no wonder we picked them as "Artists to Watch" way back in January). From Welch's flowing gowns and epic, downright ethereal voice to the harpist she employs and the fresh-cut flowers she insists on decorating her mic stand with before each show, she's sure to raise more than a few eyebrows and probably win some new fans at the VMAs next month.

And one of her fellow nominees can't wait to see her play live: B.o.B, who told MTV News last week that that he's a huge fan of Welch and is expecting big things from her on VMA night.

"Oh, man, I dig Florence so much. I listened to her perform 'Dog Days Are Over' at Coachella, and she's amazing," he said. "I hope she performs, and I hope she wins everything. I think she's awesome."

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