Pink marks 19th anniversary with Carey Hart: 'My one constant'

Pink and her husband, Carey Hart, got married on Jan. 7, 2006, and despite many ups and downs, they're still together after 19 years — which Pink celebrated on Instagram on their anniversary Tuesday.

Next to a photo of themselves smiling in ski gear, Pink wrote, "19 years ago on a beach in Costa Rica we both took a chance we weren't sure we even believed in. I'm so glad we did."

"I’ve been with you longer than I haven’t," she continued. "You’ve been my one constant. You have loved me, hated me, and loved me again. I love our story no matter what gets written. It is gritty and sweet. Thank you for being by my side all these years. I love you forever @hartluck."

On his own Instagram, Carey posted a photo of himself and Pink from Wimbledon last year and wrote, "For over 20 years we've traveled the world, made a family, and created amazing memories & life together. Not bad for a couple kids who weren't expected to amount to anything. You are like a fine wine, and I love you."

Carey and Pink share daughter Willow, 13, and son Jameson, 8.
