When your Sandra Bullock and you turn 50, you could celebrate your half a century of age anywhere, but she prefers Wyoming.

She came to Jackson Hole to party at the Million Dollar Cowboy Bar and that they did. She didn't turn 50 until Saturday, but the party started on Thursday. According to sources at the event they didn't want to create a stir and keep the party quiet. Well maybe not inside the venue, but to the local folks who are use to big names and big money rockin' their town.

Chelsea Handler and others were on hand to help Sandy turn 50 and make sure she didn't lose her GRAVITY! Most of the parties photos did end up on Instagram.
