NEW YORK -- Good news for the 203,000 people who bought Hilary Duff's Metamorphosis in its first week on shelves: The actress-turned-singer is officially taking a break from movies to focus on music.

"I will be touring, I'm practicing right now," Duff said at Radio City Music Hall while in town for the MTV Video Music Awards. "I just finished doing a movie and I've been rehearsing with my band every night after work, so maybe in November and December."

Until then, Duff will continue to promote Metamorphosis in other ways, such as with the television special "Hilary Duff's Island Birthday Bash!," which airs September 24 on the WB.

The "Lizzie McGuire" star will also release a follow-up single to "So Yesterday," most likely her favorite song on the album, "Come Clean."

"It's a little more mellow than 'So Yesterday,' but it's not really pop music," Duff said. "It sounds sort of like techno, but it's slow. It's really cool."

And although she's finished making movies for the year, Duff has two in the can. "Cheaper by the Dozen," a remake of the 1950 comedy and starring Steve Martin, Bonnie Hunt, Tom Welling and Piper Perabo, opens on Thanksgiving, and "The Cinderella Story" is due early next year.

"The Lizzie McGuire Movie," which topped the box office in April, was recently released on DVD, and sales of its soundtrack just crossed the 1-million mark (see [article id="1477832"]"Mary J. Blige, Hilary Duff Take Over Top Slots On Albums Chart"[/article]).
