When Britney Spears and Paris Hilton open their stockings on Christmas Day, they shouldn't be surprised to finda lump of coal.

A poll of American children released on Wednesday found that the two high-profile celebrities should top Santa's naughty list.

By contrast Disney star Hannah Montana was overwhelming deemed the "nicest" celebrity among children aged 2 to 12 while actress Angelina Jolie was the choice for teenagers 13 to 17.

The online survey of 1,107 children was conducted by E-Poll Market Research, which specializes in celebrity and brand research, to gauge children's attitudes about nice, naughty, and the seasonal question of who makes Santa's list.

Spears, whose stint in rehabilitation, panty-less pictures, and custody battle for her children has won headlines globally, was awarded top "naughty" honors with younger and older children.

She was followed on the list by heiress Paris Hilton who spent three weeks in jail this year on a probation violation.

The two women beat out Swiper the Fox from the television show Dora the Explorer, the Grinch from the book "How The Grinch Stole Christmas" and Darth Vader from Star Wars among children 2-12.

For teens, Spears and Hilton topped Lindsay Lohan, who spent 84 minutes behind bars this year for a drunken driving and caffeine possesion conviction, and Beyonce.

When asked what makes someone nice, children mentioned "cleaning up and doing chores," "sharing" and "being honest and polite" as ways to impress Santa.

On the flip side, they mentioned "not listening to parents," "being mean and bullying" and "being snobby" as behaviors exhibited by those headed for the naughty list.
