We're sure they were just supporting their pal, but you can't help but wonder who came just to network!

After splitting from his first wife last year, Relativity Media CEO Ryan Kavanaugh and new lady love, Sports Illustrated swimsuit model girlfriend Jessica Roffey, tied the knot in Malibu over the weekend. The famous faces in attendance included Katie Holmes, Pierce Brosnan, Steven Tyler, Tom Arnold, Edward Norton, Ryan Seacrest, Shannen Doherty, Josh Hartnett and fellow producer Jerry Bruckheimer, among others.

The event was held at Nikita restaurant in Malibu, but we have a feeling there was an after-party at Kavanaugh's Malibu pad. The billionaire producer owns a number of properties in Southern California, one of which sits on an acre of land in the 'Bu and seems like the perfect spot to have a wedding bash. Sounds like a good time to us!
