"I'm eating for two these days," Pink told DeGeneres, adding that her doctor believes she's having a daughter. "My mom has always wished me a daughter just like me. I'm terrified one of us will go to jail."The Grammy winner said she was nervous to announce the pregnancy because she previously had a miscarriage. "I didn't want to talk about it ... but if I was going to talk about it with anyone, it was going to be with you," Pink told the talk show host. "I worked for [this pregnancy]. It was not an 'Oops.'"

Pink, 31, and Hart, 35, have been married for four years. They briefly separated in 2008, but reconciled after Hart appeared in her music video for "So What," which dealt with their split."I never had anything in my life that I didn't work hard for and my relationship is that," Pink told DeGeneres. "We worked really hard and we had our little meltdowns, a couple of them. ... We both needed to do that and come back together. It's just yummy."
