The 64-year-old former boxing promoter began her transition in August 2014 and has now gone under the knife for the final time.
She said: "I'm a fully-fledged female now. I had it cut off and replaced.
"Now I'm very relaxed, happy and open about my life."
Kellie lived as Frank Maloney for more than 50 years, helping guide heavyweight world champion boxer Lennox Lewis to stardom, but went through three suicide attempts, two of which were "a cry for help", and had to face questions from her wife about whether she was gay or having an affair.
Speaking about the breakdown of her second marriage to Tracy, who she was married to from 1997 to 2012, she said: "In 2010 I was becoming withdrawn and drinking a lot.
"As a result Tracy started blaming herself.
"I'm a fully-fledged female now ... now I'm very relaxed, happy and open about my life.
"She asked me if I was having an affair and if I was gay. I said no to both and looked at her and said 'I'm the same as you; I always believed I should have been a female'.
"I regretted saying it initially because I knew our marriage would be over.
"I also realised then that there wasn't any going back."
After starting hormone replacement therapy, Kellie was keen to have an "instant success" with her body changes.
Speaking to Kent Online, she added: "It changes your figure - your breasts grow and your skin gets softer - but I wanted instant success.
"The doctor had to remind me that I needed to be on them for 18 months to two years for them to have an effect."
Last year, Kellie opened up about her struggles to find love.
She said: "Dating is a sad topic for me. I'm having problems with love. I want to date, of course, but it's hard. I've been on a few good dinner dates with men but when they realise who I am, they make up an excuse and leave or never contact me again.
"I think they're scared of being judged or it' my history in boxing - I don't know."
