Hayden Panettiere is a glowing mother-to-be -- but she recently revealed that her pregnancy weight gain has been a bit overwhelming for her.

"I'm 5 feet, 2 inches and I started out at 106 pounds and guess how much I weigh now? Around 145 pounds," Hayden told Hello! magazine. (Quotes via E! News.) "And the worst part is that my feet are still size five and they're going, ‘What's going on with all this weight?' They're about to snap from underneath me with the strain."

She added, "I'm still quite muscular, so if you're running around carrying 40 pounds of extra weight, you're going to build extra muscle."

However, the actress couldn't be more excited to be a mother, telling Hello!, "I'm so ready to hold my baby girl — I'm going to be a very hands on mom. I'm thrilled that I am having a girl first because I feel like I know a lot about raising a strong woman. I feel very empowered myself and I think my daughter will, too."

Hayden sounds like she's going to be an amazing mom! See Hayden and other celebs reveal their sizes in the gallery above!
