Mariah Carey was left squirming in her seat during her appearance on Ellen DeGeneres' talk show - after the comedienne quizzed her over pregnancy rumors.

The singing superstar was a guest on the program on Tuesday to promote her new single, I Stay In Love. But the cozy chat soon became uncomfortable for Carey, when funny-woman DeGeneres popped open a bottle of champagne in a mock pregnancy celebration.

And the stunned superstar, who recently insisted she would keep any baby news secret, fueled rumors she was pregnant with husband Nick Cannon's child when she refused to drink the alcoholic fizz.

A shocked Carey said, "I can't believe you did this to me, Ellen. This is peer pressure!" But DeGeneres didn't let the issue go, asking the Grammy-winner again if she was with child, to which Carey replied, "I can't believe her... I didn't say that. No, no, no. My mother would be at home like, on the computer like, 'What are you talking about?' We will let you know when we're going to have a family."

Carey revealed earlier this month she only considered becoming a mother after marrying Cannon in April: "I've changed my mind because I am with The One. I think we would make good parents, and that we'd be able to figure everything out together."
