By comparing her second pregnancy to her first, Kate Hudson seemed to think she could accurately guess the gender of her impending baby. In fact, Hudson predicted that seven-year-old son Ryder will soon have a baby sister, she said on 'The Ellen DeGeneres Show' (weekdays, syndicated).

"Everything's been so different, which is why I think it's a girl. And it definitely doesn't belong to me anymore -- this area," said Hudson, gesturing to her stomach. "It's all hers. So, I feel like that means it might be a girl."

And, physically, this pregnancy is much more demanding than her first, leaving her constantly drained. "I get really exhausted," said Hudson. "More tired, more sick, more everything."
