Playboy Cover Combat: The Girls Next Door vs. Aubrey O'Day!

The Aubrey O'Day nude watch is officially on, as the singer has released her first comments about the upcoming photo spread.

"I'm honored to be a part of the Playboy legacy and look forward to my March cover hitting newsstands on February 13," O'Day told Us Weekly.

The singer's Playboy debut will follow the February issue of the magazine, which is billed as a farewell for The Girls Next Door.

Look for Holly Madison, Bridget Marquardt, and Kendra Wilkinson to be featured in the publication in a special three-cover release. (They've been replaced in Hugh Hefner's bed by the Shannon twins and Crystal Harris.)

"I directed and produced the shoot,” Madison recently said. "I’m really proud of that... I’m just excited to have shot and produced the shoot myself."
