Hottest Party For NYE Goes To...

Jay Hova!

The Hip Hop mogul took over the Cosmopolitan Hotel as he headlined with Coldplay for a intimate concert.

The concert was the center of the opening festivities for the new resort.

It was a star studded celebration as Christina Millian said, "I think its going to be power house tonight."

Singer Brandy told Hollyscoop, "Very excited about J- very excited about Coldplay. They are great artist, I am just looking forward to being inspired tonight."

Glee star Mark Salling mentioned that he wouldn't mind collaborating with Jay Z or Coldplay.

The stars watched Coldplay kicked off the evening with a 12-song set. Later on, Jay Z joined Coldplay on stage for a rendition of Lost, followed by a countdown to midnight. Coldplay then ended their set with crowd favorite Viva La Vida.

The first hour of 2011 brought plenty of surprises as JAY-Z took the stage. He was joined by Kanye West for an impromptu freestyle performance of Run This Town, Can’t Tell Me Nothing and Runaway. Then as Kanye left the stage, John Mayer joined pal JAY-Z with his guitar for several songs, including Public Service Announcement and 99 Problems.

The ultimate collaboration of the evening came when Beyonce joined her husband on stage for Young Forever. She continued to wow the crowd, bringing Coldplay front man Chris Martin back out for an acoustic duet of her hit, Halo.

The show came to a close as JAY-Z, Kanye West and Chris Martin came together for Kanye and Chris’s original collaboration, Homecoming. The crowd then sang along as JAY-Z performed Empire State of Mind and finished his set with Encore.

Gossip Girl star Jessica Szohr exclaimed at concert, "Living in new York, Empire State of Mind was a really big hit everywhere, but New York has such a special place in my heart."

To say the least, “You will never get to see this again,” as JAY-Z summed it up best.
