Carey Hart paid special tribute to his wife P!nk on Sunday, honoring her on the occasion of her 40th birthday.
"Welcome to 40 baby," he wrote as a caption for a sexy black-and-white image of the couple on Instagram. "I’ve celebrated 18 birthdays with you, and I can say it’s amazing growing up with you. The person you have grown into is inspiring. You have become a successful business woman, superstar, dedicated mother, Philanthropist, supportive wife, wine maker, motorcycle mama, and amazing friend to all around you. I’m so proud of the woman you have become, and you are more beautiful than ever. You truly are like wine. You just keep getting better, and I’m so lucky to be along on this crazy ride with you. I love you baby. Looking forward many many more birthdays with you. I can’t wait to see how nuts you and I are in our 80’s 😂😂. Enjoy your day."
P!nk and Carey have been married since 2006, and are the parents of Willow Sage, 8, and Jameson Moon, 2.
Though they separated for a spell in 2008 and have been in therapy for most of their time together, P!nk has said their shared childhood experiences as children of "broken familes" has bonded them.
