Pink And Carey Hart Celebrate Six Years of Marriage

Congrats to singer Pink and husband Carey Hart who are celebrating six years of marriage!

After a long string of celebrity break ups and divorces, we have pretty much lost faith in celebrity marriages, but that doesn't mean we aren't impressed with the couple's six-year-marriage or their adorable display of affection on Twitter.

On Saturday, Hart tweeted:

A sense of humor is obviously key to their relationship. Pink tweeted back:

The singer, whose real name is Alicia Moore, married Hart in 2006, on the beach in Costa Rica. Together they welcomed their first child, daughter Willow Sage in June 2011.
