It’s a big night for Brit!

Wednesday is the long-awaited first live show of Fox’s The X Factor (8 p.m. ET), and Britney Spears, 30, has mixed emotions about the experience.

“I am a little nervous,” the pop star told Extra’s Terri Seymour. “But I’m excited. I’m really, really excited. I can’t wait.”

Spears will be joined by fellow judges Simon Cowell, Demi Lovato and L.A. Reid.

According to Cowell, the pop star may dress as a witch for the occasion – and for Halloween – though Spears says viewers will have to wait and see to find out what her costume will be. But Spears does expect some special guests to forgo trick-or-treating to be in the audience for the big night.

Of sons Sean, 7, and Jayden, 6, Spears says, “I think they’ll probably come to the show, yeah.”

“Working up a spell against Simon Cowell’s groups… muaha ha!”

What do you think it is??  She says it’s picked out and wants to know what everyone else is being.

Last year she was on tour during Halloween and shared a pic from backstage.  She’s probably excited to dress up this year!

Remember her witch costume in 2008?

Britney posted these pics on her official website!!!

Look at these EXCLUSIVE pics Britney sent us of her and the boys from Halloween night.

Brit, her friends Courtney and Laura Lynn, her assistant Brett and dad Jamie took the boys out trick or treating before heading home to get ready for Drew Barrymore’s party.

Oh and dear X17 and TMZ… those pics you posted over the weekend of “Britney” as a fairy… Yeh, sorry to disappoint but that’s not Brit.. It’s Courtney. You’d think after all these years of stalking Britney you’d be able to tell the difference.

No, Britney hasn’t wigged out!!  She  was photographed after having attended a Halloween party Friday night at  George Maloof’s house.
