Pink and Carey Hart

In 2005, the ‘Just Like Fire’ singer, 43, took advantage of the motocross Pro 250 finals, where her now-husband, Carey Hart, was competing to pop the question.

By the third lap of the race, Pink held up a board that read: “Will you marry me?”, followed by another one where she wrote: "I’m serious!”.

Pink and Carey have been married since 2006, and have an adorable family which includes children Willow, 12, and Jameson, six.
