The 29-year-old actress opened up about her dating life in a February interview with Cosmopolitan, revealing that she's not "desperate" to find a boyfriend after her divorce from Mike Comrie, with whom she shares 5-year-old son Luca. 

"I've never been a good dater," Duff confessed. "I meet, like, one person a year that I'm maybe attracted to. I never want to be that girl who's desperate to find a mate."
