Pink has marked 19 years of marriage to her husband Carey Hart.
The couple have been married since 2006, after tying the knot in Costa Rica.
In 2008, they briefly separated, before later reconciling, which they attributed to couples counselling for making their relationship work, and helping them to communicate with each other.
Taking to Instagram, Pink reflected on taking that "chance" which saw they marry in 2006.
"19 years ago on a beach in Costa Rica we both took a chance we weren't sure we even believed in", Pink said. "I'm so glad we did. I've been with you longer than I haven't. 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".
Pink's husband Carey Hart, a motorcross racer, also took to social media to celebrate the milestone.
"19 years married today to this amazing woman @pink," he said. "For over 20 years we've travelled 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".
The couple have been together since 2001, and share two children, 12 year old daughter Willow, and 8 year old Jameson.
