Christina Aguilera marked off her birthday with a big life change. After coaching "The Voice" for its first three seasons, she left the hit series the day she turned 32.

It ended up being Blake Shelton's contestant Cassadee Pope who won Season 3 instead of one of Aguilera's singers, but that didn't stop her from going out with a smile. "Thank you Fighters for the many sweet birthday messages today! Let There Be Love to you all! XoXtina," she tweeted to all her fans wishing her a happy birthday.

Aguilera isn't the only big Hollywood celebrity to have a birthday on Dec. 18. Brad Pitt turned 49 yesterday and Katie Holmes turned 34. For her part, Aguilera looked forward to aging another year.

"I am enjoying being a woman now. Every year I think, this is going to be a great year, a new chapter. And it is," she told ABC News in October. "I enjoyed being young but I would never relive my teens. Those are hard years for everyone."
