Duff, 27, who separated from her husband early last year, explained how she is juggling caring for her three-year-old son, launching an album, planning a tour and filming a television series so love is the last thing on her mind, reported Contactmusic.
"I'm not bitter about love or anything like that. I'm so busy right now - honestly I don't have time to date and to be building some kind of a relationship.
"I have a 3-year-old, I have a new album, I'm sure you know what it takes to put a record out and make it work, and build a tour and shoot a TV show, all this stuff! If it came my way and it was easy, sure I'd be into it but it's not something I'm stressed about," she said.
