It's an open secret that Perez Hilton can't be bothered to blog all day long anymore. But for some reason he's never copped to using ghost writers. Until now.

Hilton (né Mario Lavandeira) is being sued for breaching a legal settlement that prevented him from mentioning Jonathan Lewandowski (a/k/a Jonathan Jaxson), the young blogger from whom Hilton allegedly solicited sex tapes in exchange for promoting Lewandowski's blog. When Lewandowski's name cropped up in a post on February 3, he claimed Hilton had violated the agreement. But Hilton was shocked — shocked! — that someone assumed he wrote PerezHilton.com. You see, it was really his sister, Barbara, who wrote the item.

A tipster forwarded us the lawsuit, which was filed on Wednesday in Los Angeles federal court and you can find in full here.

His lawyer wrote in a letter to Lewandowski's counsel that Hilton's sister wrote the post:

Hilton has hinted at his sister's involvement; he told Time that he worked on the site with his "sister, who's my assistant and helps a little bit." But this is the first time he's confirmed that he has a full-on ghost writer.

Guanabee, meanwhile, has reported that Hilton has had other ghostwriters going back to 2006.

Which wouldn't be a scandal, if Hilton were to only acknowledge the help he gets. Yet he continues to hide the making of his gossip sausage, as though his readers are deeply invested in his oh-so-elegant image as an articulate man of letters and glamorous Hollywood gentleman. Hilarious.
