Lisa Kudrow hosted the UCLA Semel Institute's Open Mind Gala [1] at The Beverly Hilton Hotel on Wednesday, where she happened to bump into an old friend (pun totally intended, by the way): Courteney Cox [2]. The former Friends [3] costars looked incredibly happy to see each other, sharing a hug and a dinner table. After posing for photos with fellow attendee Demi Lovato [4], Lisa addressed the crowd at the philanthropic event — which raises money for mental health research, education, and clinical care programs at UCLA — as Courteney looked on in the audience. It might not be as fun as an afternoon gossiping at Central Perk or a "Smelly Cat" jam session, but we'll take what we can get.
