Vinny Guadagnino's family considers Pauly D one of their own. So it should have been no surprise when Vinny showed up to see his Jersey Shore pal spinning for his monthly residency at Haze Nightclub at Aria in Las Vegas.
Except Vinny brought his mom!
"Pauly welcomed Vinny’s mom Paula into the DJ booth and introduced her to the crowd as his second mother while everyone cheered," an eyewitness at the March 23 event tells OKMagazine.com.
"She left after about 30 minutes and the boys hung out together until Pauly was done with his amazing set."
It's pretty impressive that Vinny's mom (seen with Pauly D above) was down to party with her boys until 2:30am!
Earlier in the evening, Vinny had dinner at Fix with his girlfriend, MTV's Melanie Iglesias, and mom Paula. The trio also took in Cirque du Soleil's show Zarkana.
