celebrated his first day of work on Two and a Half Men
with wife Demi Moore
and a big group of friends at Trousdale Lounge
in L.A. – and the couple looked "happier than ever," says an onlooker. Kutcher was the life the party, cracking up his friends with jokes, but also snuggling with his wife during the lively night out.
Also at Trousdale
that night: Lauren Conrad
, who seemed focused on pal Lauren "Lo" Bosworth
and not at all fazed by the presence of ex Kyle Howard
. In fact, the two were friendly, though they didn't appear to flirt or have any physical contact during the night out with friends.
and Katie Holmes
joined his Rock of Ages costar Russell Brand
at Katy Perry's
Los Angeles concert at the Nokia Theatre at LA Live. Russell walked slightly ahead of the couple, who held hands. They all posed for photos with fans lucky enough to spot them.
