The 60-year-old actress has lost 100 lbs since appearing on 'Dancing with the Stars' last year and she admits her new figure has given her the confidence to find love again and be more adventurous in the bedroom.
She said: "I didn't like the way I looked, and I didn't want to have fat sex!
"What I'm looking for is to be madly, deeply in love. For the first time in my life, I know exactly what I want in a man. I want someone who has my back, who is courageous and brave."
Kirstie - who has previously been married to Bob Alley and Parker Stephenson - insists, for her, there was "nothing positive" about being overweight, and now she is a US size six she has more energy than she's ever had in her life.
She added in an interview with People magazine: "I have more energy than I've ever had in my whole life. My body had gotten really weak. There was nothing positive about being fat. I feel back to normal. I have my game again."
