A stint on "Couples Therapy" is meant to renew existing romantic relationships, but for Deena Cortese, it's forming new friendships, too!

The former "Jersey Shore" star, who'll appear on the next season of "Couples" with boyfriend Chris Buckner, seems to have a brand-new bestie: porn star-turned-media-personality Jenna Jameson. The blonde bombshell will also be appearing on the hit VH1 series (with boyfriend John Wood), and in the pic above, it seems as if the ladies did their own bonding on set.

"Me and my girly ❤️ @jennajameson," Deena tweeted yesterday, which officially marked the end of the season's filming. The pals look like two peas in a pod! But does D's old meatball-in-crime Snooki have reason to be concerned? Eh, we'll put our worries aside until Jenna joins the guidette for a hot tub adventure.

+ Surprised to see Deena and Jenna chummin' it up? Share your thoughts, and be sure to see how this friendship takes shape on the next season of "Couples Therapy," premiering September 10 at 9/8c on VH1!
