Buckle up, Hannah Montana!

In a blog item posted Monday, Consumer Reports magazine says 15-year-old superstar Miley Cyrus, who plays Hannah Montana on television, is seen in her new movie riding without a seat belt in the back seat of a Range Rover.

So is her father, Billy Ray Cyrus, the Yonkers-based magazine says.

The movie is the 3-D Disney concert film "Hannah Montana & Miley Cyrus: Best of Both Worlds Concert," which is based on Miley Cyrus' TV show and has made more than $50 million in less than two weeks.

Telephone calls and e-mails to Disney and to several of Miley Cyrus' representatives, seeking comment, were not immediately returned Monday.

The magazine says 65 percent of the 13- to 15-year-olds killed in auto accidents in 2006 were not wearing seat belts.

"It seems to us that Miley, her father and Disney had a perfect opportunity to help influence teens and counteract -- rather than encourage -- this trend," the blog item says.
