Hayden Panettiere had to stop her mother selling her underwear on the internet.

Hayden Panettiere stops mom from selling her panties

The Heroes beauty has been raising money for Save the Whales by auctioning her old clothes on website Panettiere's Closet. But Hayden says she has had to draw the line on some of her smaller items of her wardrobe. "I lived with my family a long time so you acquire a lot of stuff with nowhere to put it so I tend to throw stuff out," explains the actress. "That's when I decided to put it on the website. Mom pulls out some embarrassing stuff I used to wear. I'm like, 'Just don't pull out the underwear!'"
