The 60-year-old actress joined ABC's reality competition show Dancing with the Stars last season in March 2011, where she finished in second.
Alley has said that her appearance on the show helped her lose weight, dropping to almost a size 6 (US) / size 10 (UK).
When asked if her new figure has helped her love life, she answered that right now she is just dancing and not dating.
Alley told In Touch: "I always think when somebody really wants something, it will happen, and I sort of half-assed want something.
"It's not my priority right now. I'm really having fun dancing and working, and helping my friends and their charities. It's great to have a tool to use to help raise funds for different great causes. I'm excited about that."
Alley's appearance on Dancing with the Stars inspired current contestant Ricki Lake to join the show.
