Following the release of her fourth studio album, Dignity (2007), Duff released a greatest hits album and parted ways with Hollywood Records.
Duff began working on numerous projects with the Disney Channel, including the film Cadet Kelly (2002).
She later began work on an album, releasing the Christmas themed Santa Claus Lane (2002) through Walt Disney Records.
Duff began to expand her career into theatrical films, with leading roles in projects such as Agent Cody Banks (2003), Cheaper by the Dozen (2003), A Cinderella Story (2004), and Cheaper by the Dozen 2 (2005).
She continued to have success in music, with her albums Hilary Duff (2004) and Most Wanted (2005) achieving Platinum status in the United States.
A source told the publication that the split was down to "busy schedules" and claims that Matthew is very much "single" as he continues with his tour.
It has since been reported that the 29-year-old actress has rekindled her relationship with her former partner, personal trainer Jason Walsh.
Duff was previously married to former professional hockey player Mike Comrie.
It looks like former Disney star/current cool girl Hilary Duff has a new boyfriend, and he's not just a businessman, he's a business, man (sorry).
Duff began her acting career at a young age, and quickly became labeled a teen idol as the title character of the Disney Channel comedy series Lizzie Mc Guire (2001–2004).
