Dinner and dancing – that's what was on the agenda for Jessica Alba
and husband Cash Warren
– and they kept interesting company for their date night out. The new parents
enjoyed a private meal at Mr. C Beverly Hills along with an eclectic array of people. Joining them: Jeremy Piven, Tara Reid, Elisabetta Canalis
and Joe Jonas
. According to a source, Jessica and Cash sat next to each other at the restaurant, and everyone at the table was in a great mood. After the invite-only dinner, the whole group headed to The Beverly afterward to continue the party, where the party shared another table – when they weren't hitting the dance floor.
