Pink and Carey, 41, have had a lot of ups and downs since they they first got together in 2001. They briefly split in 2003, but then she proposed to him in June 2005. They married in January 2006, broke up in 2008 and reconciled again in 2010 after attending marriage counseling. In June 2011, Willow was born.

Earlier this year, Carey shared a loving message for his wife on their 10th anniversary on Jan. 8. Along with a photo of them and Willow by a fireplace, he wrote, "Happy anniversary to my MUCH better half. 10 years is a pretty amazing milestone for 2 misfits like us. I'm proud of us baby!!! Thank you for being an amazing wife, mother, and friend. I love you."

Being a mother has also given Pink a new perspective on life. In December 2015, she told People magazine, "I have lived a lot of life in a very short time, and you get hardened a little bit — you get jaded, you build up walls. And when you see this little kid, and you get to watch them through infancy to toddler to little person, it's amazing."

Congrats to Pink and Carey!
