Heidi Montag has given the world a sneak peek of her forthcoming Playboy spread.

The reality TV star proudly held up the September issue of the magazine with herself on the cover as she walked the red carpet at the Los Angeles premiere of G.I Joe on Thursday.

In the cover photo, Heidi appears tanned and well-oiled as she poses in a white bikini with the iconic bunny symbol etched on her midriff.

The 22-year-old is said to have received in the region of $500,000 for her modelling services, in a deal reportedly masterminded by new husband Spencer Pratt.

Though the rest of her spread remains underwraps for now, Heidi previously revealed that Hef hadn't persuaded her to get completely naked.
