Kelly Clarkson has opened up about her difficult pregnancy, revealing she vomits up to 12 times a day and her hair is falling out. The singer is expecting her first child with her husband, Brandon Blackstock, and she had to announce the news early after a bad bout of morning sickness prompted her to cancel a promotional appearance. Clarkson has now revealed her symptoms are more serious than she previously admitted. During an appearance on U.S. TV's The Ellen DeGeneres show, Clarkson revealed she had vomited just minutes before stepping out in front of the cameras, telling the host, "I vomit a good dozen times a day, it's, like, bad. Like, I vomited before coming out here and I had a peppermint so you didn't (know)... I'm not even kidding, it's so bad. It's so bad. I know, it's, like, so gross." Clarkson went on to reveal she is also suffering a number of other nasty side effects from her pregnancy: "That's the thing too, you're not attractive when you're pregnant. Like everybody tells you you glow and you're hair is pretty and you're nails are pretty. That is total c**p. My nails are short, my hair still falls out like it's not all lush and beautiful and I have no glow. Unless it's like something left over from a bad throw up. It's horrible." The singer also revealed she has yet to find out her baby's gender, but has picked out a uni-sex name for the child, adding, "I just want to know (the baby's gender). And it doesn't even matter because, honestly, the name we've picked, if it's a boy or a girl, it's the same name... You won't guess it. It's a random name. But it's not like... Blue Jazz. It's not going to be a weird name."
