Lindsay Lohan will promote her upcoming nude Playboy pictorial on ‘The Ellen DeGeneres Show’ on Dec. 15, but have photos already leaked online?

The ‘Ellen’ appearance is the first – and only – destination Lohan, 25, has selected to help spread the word of her naked pictures taken for the magazine’s January/February issue, which will debut the day of the show. The magazine will hit newsstands later this month. The photo above is supposedly a leaked photo of the magazine cover. Looks pretty legit to us.

We’re sure Ellen will ask zero probing questions of the oft-troubled Lohan, who is pretty much a punch line with feet at this point. Actually, we wouldn’t be surprised if the two women spend an entire show segment just paging through the magazine. She might also do one of her zany games with LiLo, so one of the seven men in the world that watch the Ellen show will have to let us know if that happens.

Playboy founder Hugh Hefner said the Lohan pictorial was done as a tribute to the Tom Kelly photographs of Marilyn Monroe used in the first issue of the magazine in December 1953. Hefner, meanwhile, may not be able to tell the difference between Monroe and Lohan anymore than he knows it’s 2011 and not 1953.
