Taped footage of U.S. singer Ashlee Simpson behaving badly at a Toronto McDonald's has been aired on CTV's "E Talk Daily."

The tape shows an allegedly drunken Simpson climbing atop the counter of the fast-food restaurant, then calling the cashier an expletive when she asked her to get down, the New York Post reported Saturday.

The tape also shows the singer telling a fan to "kiss my foot" when he asked to have a picture taken with her, then refused when he did not follow her order, the Post said.

"A girl should be allowed to buy a burger in peace," a Simpson rep told the newspaper.
