Rocky TV reality couple Ronnie Magro and Sammi “Sweetheart” Giancola turned up the heat as they partied together in Las Vegas over the 4th of July weekend -- and Breaking Celebrity News has the exclusive photos.

Despite recent reports that their relationship had some tough times during filming for season two, the Jersey Shore lovebirds definitely looked like they’d put their differences behind them,  as they stared deep into each other’s eyes while sipping champagne on the dance floor of the Jet nightclub last Friday.

Their sexy canoodling didn’t end in Sin City.

The couple then traveled to San Diego together on Saturday to spend the rest of their romantic reunion in Southern California with friends.

Ronnie and Sammi’s rollercoaster relationship was a constant source of drama during the first season of Jersey Shore.

The fireworks continued in January’s reunion show, where Sammi stormed off stage after a clip showed her in bed with Mike “The Situation” Sorrentino.
