Gwyneth Paltrow & Cameron Diaz BFFs on New Year’s Eve

Gwyneth Paltrow and Cameron Diaz rang in the new year together along with an A-list crowd at the grand opening of the Cosmopolitan of Las Vegas.

The two blondes were part of the elite group gathered in a private VIP area at the boutique hotel for the powerhouse performances of Coldplay and Jay-Z. While Gwyneth’s hubby and his British band took the stage, the Country Strong star — in a skin-tight dress — sipped wine and danced with her new BFF Cameron, who was accompanied by her Yankee star boyfriend Alex Rodriguez.

To the left of the blonde bombshells, a very sparkly Beyoncé and Jay-Z watched the show — before H.O.V.A. himself took to the stage. Also there? Rihanna, who — having recently split with beau Matt Kemp — got her groove on with some girlfriends.

Other stars making the scene included Blake Lively, Kellan Lutz, Ellen DeGeneres, Samantha Ronson, Channing Tatum, Giada De Laurentiis and Glee’s Mark Salling.

The action on stage was equally star-studded! After Coldplay kick-started the party, Jay came on at midnight with a giant clock to countdown the New Year and bring in 2011 with a shower of confetti. Coldplay returned to finish their set and Jay-Z joined them, calling up some of his favorite musician pals — including Kanye West and John Mayer — to join them.

The duet of the night was undoubtedly when Jay-Z’s gorgeous wife, dressed in a festive sequined silver and white dress, joined him to sing “Forever Young” and “Halo.”

When Chris was done with his musical obligations, he spent the rest of the show standing protectively behind Gwyneth, who ditched her sky-high heels for a portion of the night so she could dance. When it came time for them to leave, she had to lean on her hubby as she tried to get her shoes back on.

As for Cameron, she seemed partied out as she left at almost 2am. With smudged red lipstick and tangled hair, she was guided out of the packed venue by A-Rod and their security detail.
