The 33-year-old raises two-year-old daughter Willow Hart with husband Carey Hart, reported Contactmusic.
"I had moments where I wanted a kid with Carey. You know - you fall in love and you're like, 'We should have kids,' and then it went away.
"But he always wanted kids and now it's like so good. It's more important than anything we've done," she added.
Despite her huge success, Pink insists fame hasn't changed her and she loves to start her day with a hug from Willow, which she calls "the best thing in the world".
