Brothers & Sisters set tv show wedding dress crew

Brothers & Sisters Balthazar Getty sweatshirt jeans starbucks

Okay, I'll admit that Balthazar Getty is a genuine hottie... but with all that gray and white hair, he's starting to look like Santa Claus!

The Brothers & Sisters star was filming his TV show in Malibu the other day and later grabbed some Starbucks - guess he needed a caffeine boost, 'cause he bought two cups of coffee!

Sidebar, what is UP with him and Sienna Miller??? Are they over for good? First she gets together with that DJ Slinky Wizard guy (yeah, he's a real catch!) and on Monday there were rumors of a reunion with Jude Law. She really gets around!
