Taylor Swift Squeaks in Beat Box Spot for Grammys (watch!) 1Country queen Taylor Swift has been known to cross over audiences with her music, but she should draw the line on rap. Despite LL Cool J’s best efforts, Swift squeaks her part in a new Grammy commercial.

Still it looked like it was good fun, and Taylor, 22, seems to have no problem laughing at herself at the end of the 30-second spot.

Cool J, 44, will be hosting the 2012 Awards show, and Swift will be one of the feature performers along with Katy Perry, Adele, Rihanna, Coldplay, Paul McCartney, Bruno Mars, Kelly Clarkson, Jason Aldean and Nicki Minaj .

Swift looks sassy in the spot for the Feb. 12 show. She’s wearing a little black cocktail dress with a plunging neckline and her hair is straight with bangs.

Cool J starts things off with a steady beat and tossed to Taylor, who joined in with some springy boings. The sound is probably closest to the metallic sound of a Jew’s harp. But she quickly loses the beat.

“Oh my god,” Mr. Cool says.

The spots goes the only place it can go; Cool J breaks out in laughter and Swift quickly follows. “I love it,” he laughs. Swift can’t keep it together either. Nonetheless, she looks super hot.

She’ll be joined on stage by Bruce Springsteen and Adele, 23, will be making a comeback from throat surgery.

“It’s an absolute honor to be included in such a night, and for it to be my first performance in months is very exciting and of course nerve-wracking, but what a way to get back into it all,” she said in a statement.

If the show can keep it as loose as its commercial, it might actually be worth watching. The Grammys air Feb. 12 on CBS. Check out the video below.
