Spencer Pratt and Heidi Montag

Always one to take advantage of the spotlight, Heidi Pratt debuted her September Playboy cover at Thursday's G.I. Joe: The Rise of the Cobra premiere, where her husband, Spencer, proudly admired his wife's (photo) spread.

The duo didn't give photographers a peek of the inside shots, but the cover displays Heidi, who appears to be coated with mud, in a white bikini with a Playboy bunny sketched out on her midsection.

The Pratts declined to comment on the issue, but frenemy Lauren Conrad has no problem voicing her opinion. Referencing Heidi's cosmetic enhancements, the ex-Hills star recently quipped, "They're not going to pay for themselves."

What do you think of Heidi's cover?
