Hayden Panettiere has had to stop her mother from selling her underwear on the internet, according to Showbiz Spy

The Heroes hottie, 18, 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 the smaller items in her wardrobe.

She says, “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.

“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!’”
