Hard Rock Hotel hosted a crowd of celebs for its private party Saturday night. It was the second grand opening of the week for Wasted Spaces the night club co-owned by Carey Hart aka Pink’s ex-hubby.

The main attraction of the night was an acoustic performance by former Bush frontman Gavin Rossdale, hubby of Gwen Stefanie. He did a version of Bush’s “Glycerine” and “Love Remains the Same” off his new album.

Another attraction that garnered lots of attention was the grand entrance of Paris Hilton hanging on the arm of her boyfriend Good Charlotte guitarist Benji Madden. They rolled in shortly before 1 a.m. and did not stop at all to talk to reporters!

Carey Hart had this to say about the setting up and running of the club:

“This came out exactly how I thought it would. The great thing is the Hard Rock gave me so much freedom, and really understood and trusted the concept I wanted to do,” Hart said. “In the very end, they’re completely happy. There were no changes whatsoever. They were on the same page as me the whole entire time. To have that kind of trust and understanding with a massive company like Hard rock properties and a little guy like me, there’s something to be said for that.”
