Capping a whirlwind week of festivities marking the arrival of David
and Victoria Beckham
to Los Angeles, superstar duos Tom Cruise
and Katie Holmes
and Jada Pinkett Smith hosted a gala private party
Sunday night for their British pals at the Museum of Contemporary Art's Geffen Contemporary in downtown L.A.
"It was so much fun!" a guest tells PEOPLE.
Boasting a Who's Who celeb turnout, including Demi Moore
and Ashton Kutcher
, Brooke Shields and husband Chris Henchy, Jim Carrey and Jenny McCarthy, Bruce Willis
, newlywed Eva Longoria
(without Tony Parker), Ron Howard, Jim Caviezel, Derek Luke with his wife, Brian Grazer and Quincy Jones, the party came on the heels of Saturday's much-anticipated American debut
of the L.A. Galaxy's newest and most famous soccer player.
Holmes and Cruise, who flew in for the weekend from Germany where he's shooting the movie Valkyrie
, drove to the party with the Smiths, and the three couples posed for photos before heading inside the decked-out warehouse space, where a deejay spun tunes into the night.
And the music struck responsive chords, with the Cruises, Smiths and Beckhams all hitting the dance floor.
On the menu were such British favorites as bangers and mash (sausages and mashed potatoes), as well as such classic American fare as burgers, fries and salad.
On Saturday, Beckham made his bow for the L.A. Galaxy in an exhibition match against the English soccer team Chelsea. There, spectators included Longoria, Mary-Kate Olsen
, Shields and Henchy, Alicia Silverstone and rocker husband Chris Jarecki, Drew Carey, Jennifer Love Hewitt and Gov. Arnold Schwarzenegger.
What they witnessed was Beckham's approximately 13-minute contribution in the second half of the game – an appearance curtailed by a pre-existing ankle injury
