Rumors are swirling that Melanie Iglesias is hooking up with her "Guy Code" co-star Vinny Guadagnino after the "Jersey Shore" star tweeted a photo showing he treated the beauty to some "fine dining."

That "fine dining" turned out to be McDonald's, as evidenced by this photo where you can see Iglesias from the neck down sitting on a bed with a grease-stained Mickey D's bag.

"Wining and dining @MelanieIglesias," Guadagnino tweeted last night.

Iglesias retweeted the "Jersey Shore" star's message on her Twitter account and said fast food is the key to her heart.

"A man who feeds me McDonald's... #keeper," the brunette stunner wrote.

Iglesias, a Brooklyn native who was named Maxim's Hometown Hotties Champion in 2010, and Guadagnino, of Staten Island, N.Y., are co-stars on MTV2's "Guy Code."

The show's blog has photos of Iglesias and Guadagnino hanging out together, which you can view here.

"Guy Code," which airs Wednesday nights on MTV2, is a show that takes elements from men's magazines and puts it in a television format.

"Need to know about everything from man-scaping to man-crushes, wing men and sexting, the rules of drinking, karaoke etiquette, and more? Guy Code will feature today's top comics, athletes, entertainers, and even some experts to make sure all the players are up to date," is how the show is described on its official website.

"Every bro knows the code," the site continues. "Some say guys are born with it, but not everyone follows the same set of guidelines. On Guy Code, we're putting people on notice!"
