The singer confirmed Internet reports, triggered by photos showing her with an apparent baby bump, that she and husband Carey Hart are expecting their first child and that doctor believes the baby will be a girl.
"My mom has always wished me a daughter just like me," Pink, 31, says on The Ellen DeGeneres Show airing Wednesday. "I'm terrified one of us will go to jail."
Asked by DeGeneres why she waited to confirm the rumors until now, Pink said, "I didn't want to talk about it because I was just really nervous and I have had a miscarriage before."
As for whether the baby was planned, she said, "I worked for it. ... It was not an 'oops.'"
