With the second season of "The Hard Times of RJ Berger" set to return to MTV on Thursday at 11 p.m. ET, the already large ensemble cast is getting past the sophomore slump by adding some star power in the way of some huge guest stars.

The first one fans can look forward to seeing is "Jersey Shore" star Vinny Guadagnino, who plays RJ's cousin in the March 28 episode. Jareb Dauplaise, who co-stars as RJ's sidekick Miles, told MTV News: "To get Vinny on the show is funny, because the episode is titled 'My Cousin Vinny.' So what more would you want than the most famous Vinny I think we got right now? So we are finally going to learn how to GTL from the original GTL member himself."

Jayson Blair, who plays RJ and Miles' archenemy Max, admitted, "You see these [reality] shows and you don't know what to expect because people are always different. I talked to him here and there at events, but when he came onto set, he was super focused and super dedicated and really passionate about acting, which I couldn't be more excited for. And he was great."

Fellow reality star Paris Hilton also dropped by the set, to the delight of Dauplaise and his family.

"Paris Hilton comes on the show, and I was lucky enough to have the scene with her, and Paris is great," Dauplaise gushed. "She's beautiful, and my mom's a big fan of Paris Hilton. Actually, my mom got to meet Paris, and they got along great!"

And [article id="1652649"]Weezer, whose Pinkerton album provides the name of the show's fictional high school[/article], also make an appearance in the new season.

"It's actually the one band that I've never gotten the chance to see live until I met them on the show, and of course I was like, 'Hey can I please get some tickets? You know, come see you guys for free?' " said self-proclaimed "huge" Weezer fan Dauplaise. "Rivers Cuomo is great. Got to go with Paul [who plays RJ Berger] to the set of 'Magic,' the video Weezer shot with B.o.B, and it was great to meet them all. Just so cool to look at these guys that you've been listening to for over a decade now."

Amber Lancaster almost didn't make the cut for Weezer's big scene. "I was, like, so mad, because I was originally not in that script, and I was like, 'I want to be at that concert! I love Weezer!' So they wrote me into that episode. That was cool. So you'll see me [my character] Jenny gets to go to Weezer."

Don't miss "The Hard Times of RJ Berger" season premiere Thursday at 11 p.m. following the "Jersey Shore" season finale on MTV.
