Those are some gams! Demi Lovato showed off her killer, in-shape legs in the promo portrait for her upcoming gig as the host of the 2012 Teen Choice Awards.

This year, Lovato is replacing ‘The Big Bang Theory’ actress Kaley Cuoco, who handled hosting duties last year. Holding the blue surfboard award that is emblematic of the show, Lovato (and her stems) look va-va-voom.

Lovato, currently traipsing across the country for auditions as a new judge on ‘X Factor,’ looks toned in her lacy peach dress, which she paired with a cropped black leather jacket and mile-high, shiny patent pumps. Our favorite accessory? Those dip-dyed pink ends. The Lovatics are likely to agree with our assessment that Demz has never looked better. This image positions her as the epitome of California cool.

The Teen Choice Awards air on FOX on Sunday, July 22 at 8 PM EST. Tune in to see Lovato as host — she already looks banging in the promo portrait.

We can’t wait to see what she wears on the actual broadcast. Since Lovato has evolved into such a fashionista in recent months, we’re banking on a few costume changes…. at least.
