Sandra Bullock Turns 50 with Help From Pal Chelsea Handler!

Sandra Bullock turned the big 5-O on Saturday (July 26) and she celebrated the special birthday with the help of friends, including Chelsea Handler!

The birthday celebrations started off on Thursday last week at the Million Dollar Cowboy Bar in Jackson Hole, Wyoming. Joining the stars were Sandra‘s younger sister Gesine and comedian Whitney Cummings.

“They said they kept it [quiet] because she sometimes likes to just act like a normal person,” a source told People about the celebration. “They came out and danced and took a bunch of pictures.”
