Gwen Stefani of the band No Doubt says she felt "gross" and "disgusting" when she was pregnant and adds that she is "very vain."
The 41-year-old ska and rock singer and her husband Gavin Rossdale, the 45-year-old singer of the rock band Bush, are parents to two boys - Kingston, 4, and Zuma, 2.
When asked what it is like performing while pregnant, Stefani told ELLE magazine: "It was horrible. Certain songs would make me want to puke. You feel pretty gross when you are first pregnant. You don't feel cute, you feel disgusting. You're getting fat. It was hard."
"I mean, I'm very vain," she added. "That would be my middle name. Of course I am, you know what I mean? I love the visual."
Stefani, known for her colorful style, is also a fashion designer and has sometimes brought Kingston to her runway shows. During her interview with ELLE, the singer slammed the styles of fellow popular music arists Lady Gaga, Rihanna and Katy Perry.
"I don't see myself in those girls," she said. "I usually put pants on. I see these girls as more going for the sex symbol thing. I was more, in the band, like a tomboy. Of course, I think every girl is sexy, so there's going to be a little of that. But I see a lot of younger artists going more toward the sexy thing."
Stefani made headlines in March when it was announced that she donated $1 million to help with relief efforts in Japan following its recent deadly tsunami and earthquake.
