AceShowbiz - Sparks between DJ Pauly D and Nikki Hall might be returning. The "Jersey Shore" star has ignited rumors that he might be giving his failed romance with the "Double Shot at Love" contestant another chance after they were recently spotted getting flirty with each other at Avalon in Los Angeles.

Pauly was serving as the DJ that night, and Nikki was standing by his side in the booth, as seen in a video obtained by TMZ. At one point, Nikki joined the crowd while enjoying Pauly's show at the club, before he took out his phone and recorded the two of them together. TMZ reported that Pauly and Nikki were "very flirty" and "all over each other." It's also stated that the two "spent a lot of time smooching."

Nikki was among the contestants vying for Pauly's heart on "Double Shot at Love". Even though the two showed strong chemistry throughout the show, the DJ ultimately dumped her in the finale of the show, though they later revealed that they continued to date after the show. Things started turning south after that, with Pauly blocking her on Twitter and Instagram.

Asked about the reason why he did that during the reunion, Pauly said, "It was just a lot -- like it was a lot. Like the paragraphs and stuff, it was a lot." Nikki quickly snapped at him, "Are you joking me? The paragraphs? ...Pauly, like seriously." She then added, "Pauly blocked me because I didn't fly out to Vegas...Bro you blocked me, because I was at work and I said I'm busy. I'm busy, and you took that personally - "I'm the busiest man in the world.' "

Pauly called "bulls**t" to the claim, alleging that Nikki indeed flied out to Las Vegas despite her previous statement.
