We're still reeling from the fact that Teen Mom's resident pasta sauce maker, Farrah Abraham, made a sexy sex video with internationally famous porn star, James Deen. But the hits just keep on coming ... and punching us in the face.

Shortly before news of her porn flick broke, Farrah tweeted a picture (which has since been deleted) of a purchase from sexy lingerie store Agent Provocateur, and rumor has it she even wore one of the skimpy outfits during her X-rated video.

A production assistant on set of Farrah and James Deen's sex scene tells The Dirty that Farrah was actually loaned the lingerie from Agent Provocateur in Beverley Hills, which means she didn't get to keep her sexy outfit. Bummer!

"[The store] charged her $400 instead of $1800 to rent it," the source reveals. "She had to leave the tags on it so they would take it back."

Hopefully Farrah stripped off her leased garments before she and James got down to business, because otherwise ... you know what, we won’t even go there.

Are you shocked that everyone's favorite Teen Mom star was loaned lingerie for her foray into porn? Hit the comments!
