Sheryl Crow – Celebrities Who Turned 50 in 2012

Sheryl Crow had a lot to be grateful for this year. Not only did she make it to her 50th birthday on Feb. 11, she was diagnosed with a brain tumor that wound up being benign.

And how did she spend this year? Working on her first country album, campaigning for President Obama's reelection, appearing on an episode of the TV show 'GCB,' and getting a restraining order against a pesky stalker.

If she's tired, we don't blame her. That's enough to exhaust someone half her age.
