Pink and Carrie Hart have been married for 18 years.

In honor of their wedding anniversary, Hart wrote a special caption to his wife on Instagram.

Along with an album of sweet photos of their time together, Racer wrote, "In 18 years of marriage to this amazing human being, we have done so much together: raised two amazing children, traveled the world, gone on adventures, loved, fought, made up, supported each other, laughed, cried, We laughed more, broke up, got back together, partied, grieved, grew up, and so much more.

"There is no one else on this earth I would rather do this with than you, we've had 22 years of each other's lives and I look forward to the next 22. Unless you kill me first. I love you, baby. !!!! Happy anniversary, @pink."

One person very eloquently commented, "I love you so much! What I've always loved about you is that you are always so honest about your relationship and its ups and downs, but it's how much you love each other and your commitment to each other that shows it."

Joel Madden and Janet Jenkins and other friends also offered their congratulations in the comments section.

Pink and Hart began dating in 2001 and broke up in 2003. They then became engaged in 2005 and married in 2006, Us Weekly reported. They then separated again in 2008 and got back together about 11 months later. They have two children, Willow and Jameson.
