Los Angeles, CA (CNS) - How many burgers does it take Audrina Patridge to fill in her bikini? Judging by her ultra-thin bod, none. But she says differently in her new promo for Carl's Jr.

The "Hills" star is seen writhing around with a Carl's Jr. Teriyaki Burger a la Paris Hilton with her previous controversial campaign for the fast food chain. Patridge is clad in a gold string bikini while on a beach in Malibu.

"To look this hot in a bikini, I've got to give up, like, everything. But there's no way I'm giving up that teriyaki burger," she says in the promo.

The new 660-calorie burger includes grilled pieces of pineapple in addition to the meat and cheese.
