Can't Get Enough Of The Duffs? Just Wait

Hilary, Haylie pack their 2005 schedules with movies, music, TV.

Celebrity sisters Hilary and Haylie aren't spending a lot of time sitting around on their ... uh ... duffs.

Hilary Duff will follow up her gig as a presenter at the April 2 Nickelodeon Kids' Choice Awards by filling in for "The View" co-host Elisabeth Hasselbeck while the former "Survivor" contestant goes on maternity leave (see " 'Hilary Duff Is A Loser And A Chicken,' Harvard College Paper Says"). Then on the last weekend of April, she'll shoot a video for a still-untitled single that's expected to appear in her next film, "The Perfect Man."

In it, Hilary tries her best to set up her single mom, played by Heather Locklear, on a date. The movie is being directed by Mark Rosman, who was also behind the lens for Duff's "A Cinderella story" last year. The comedy is due in theaters June 22 (see "Wanna See Hilary Duff Act Like A Bitch? Here's Your Chance").

After that, Hilary's fans will have to wait until August, when a new album is due. Though it's scheduled to be a collection of hits, so far four new songs are slated to be featured, including the single she's about to make a video for.

With the sibs' Ice Breakers commercial already in the can and work on their joint film "Material Girls" under way, Haylie isn't getting much of a break either (see "Duff Sisters To Channel The Hiltons, And Possibly Madonna, For 'Material Girls'").

"I'm shooting 'I Remember' and doing 'Material Girls' and we're doing school," the exhausted elder sister said. The former is a thriller in which she stars with Jamie-Lynn DiScala ("The Sopranos"), Lori Petty ("A League of Their Own") and DJ Qualls ("Road Trip"). "And then I shoot a movie in Costa Rica called 'Surf Schools.' "

Haylie also contributed to the "Family Guy Live in Las Vegas" CD/DVD set that's due April 26, adding music and comic relief to television's crazy cartoon family the Griffins. With all of this, Haylie said her own album has taken a back seat. "I haven't really been working on it," she confessed. "We've been doing so many other things. When it's time to do it I want to really sit down and focus on it."
