Kelly Clarkson is battling severe morning sickness.

The 'Stronger' hitmaker, who is expecting her first child with her new husband, Brandon Blackstock, next year, confessed she is experiencing non-stop nausea as she is still in the first trimester.

The 31-year-old star told America's 'TODAY' show this morning (26.11.13): ''I don't know why they call it morning sickness. That's my big joke right now because it's all day and all night. I am super-excited about being pregnant, though. I'm just looking forward to the second trimester . . . they say it's better.''

Kelly, who was very open in the past about her desire to start a family, also explained why she decided to share her happy news so early in her pregnancy.

She said: ''We were trying to wait until the end of my first trimester because you're supposed to, I guess, because you're less likely to have a miscarriage. But everybody kept talking about it and I had to cancel something because I've been so ill. I didn't want people to think I was cancelling because I'm lazy or something, so we just told people.''

The singer believes she is having a baby girl and has already picked a name.

She said: ''Well, it's a gut feeling, too, because she's killing me. And of course it's a girl, right, causing the trouble. So, it's gotta be a girl.''

Asked about the name, she added: ''We're not saying because I don't want someone stealing my baby name and I'm so early. We named our kid before we were even pregnant.''
