Some of Alaska's runway work has been shaky this season, but last night she was the big winner, wowing the judges in not one, not two, but THREE runway challenges.

She nailed the Beverley Hills brat in the "Sweet 16" look; gave up some "Executive Realness" in a tailored power-pantsuit and razor-sharp pixie wig; and was all kooky sweetness for the big "Candy Extravaganza" challenge, sporting a pink mini-dress (and matching topper) that screamed "cotton candy."

Guest judge — and fab-tacky fashion-designer legend — Bob Mackie LOVED Alaska's look, seemingly swooning over our girl's skinny bow-legs, and declaring her "a star from the crotch down."

All of this put Alaska snugly in the final three, with the winner to be decided next week. Could TV do the unthinkable — award the top prize to Alaska, whose boyfriend Sharon Needles won it last season? Certainly, Pittsburgh would love having such a Power Drag Couple.

At worst, Alaska's going to come in third, and that's nothing to shed drippy mascara tears over.
