Celebrities including Adam Lambert, Ashley Greene, David Arquette, Balthazar Getty, James Van Der Beek, and Laura Carmichael celebrated the opening of new Los Angeles hotspot, Hooray Henry's, on Wednesday (07.08.13).

The stars joined John Terzian, Brian Toll, and Markus Molinari of the h.wood.group as they launched their latest venture which has been described as ''an aristocratic manner in London being taken over when the parents aren't home'', where guests were entertained by The Dolls and DJ Mia Moretti and treated to cocktails such as Royal Fashion and The Oxford Lad.

Speaking at the launch, Adam said: ''They have such a great track record and their other clubs are such family affairs. Always relaxed but still glamorous and they have such fun people. I think this one will be the same but just adding some British charm. I'm excited about it.''

This is the newest Los Angeles club for the h.wood.group, whose other hotspots are frequented by stars including Katy Perry, Robert Patterson, Kristin Dunst, Eva Longoria, Diddy, Jenny McCarthy, Julian Hough, Carmen Electra, Liam Hemsworth and Zac Efron.
