During the week, she's up in Canada shooting a new movie in Toronto. On weekends, she flies back to Los Angeles to work on her new album.

Duff writes in her web site's online journal, "This last weekend I recorded a new song called "Weird" which is an amazing song for my new album." She also says, "I hope you guys like the new single I've recorded together with my sister Haylie called 'Our Lips are Sealed.'"

The song is a cover version of the Go-Gos' 1981 hit, and the track's accompanying video makes it MTV premiere on May 31. The song is also featured on the soundtrack to Hilary's upcoming movie, "A Cinderella Story," opening July 16.
