EXCLUSIVE! What Went Down When Jennifer Aniston Partied With Snooki? We Have The Details!

OMG! Jen met the Jersey Shore cast Monday night! Did Snooki give her tanning tips? Did Vinny talk about GLT? Did The Situation make her feel his abs? Find out here!

We were speechless when we heard that Jennifer Aniston was hanging out with the Jersey Shore cast in Hollywood June 6, and had to find out more about what went down during their epic meeting, especially after Snooki, Jwoww & the rest of the GTL crew all tweeted how much they loved meeting her!

Sadly, Jen, 41, wasn’t at Hollywood hotspot Trousdale to get tanning bed tips from the kids (she gets her tan the REAL way, filming Just Go With It in Hawaii!) — she was there to hang out with a pal who produced MTV’s dirty puppet show Warren the Ape.

“Jen was there to support an old friend,” one insider tells HollywoodLife.com exclusively. “She’s the consummate best friend. She was keeping a really low-profile, but she did take photos with the cast of The Hard Times of RJ Berger. Everyone loved her.”

Adds an eyewitness, “Jen was hanging out with her producer friend and one other woman all night. She sat at a VIP table near the DJ booth and nibbled at some snacks like mac & cheese and sliders. She was in a good mood and very friendly to everyone, including the Jersey Shore cast and [The City star] Kelly Cutrone, who stopped by her booth to say hi.”

Damn! We wanted to hear that Snooki taught Jen how to do a poof or at the very least, that The Situation taught her how to FIST PUMP!
