After weeks of denials, The Biggest Loser trainer Michelle Bridges has finally revealed she is romantically involved with her co-star Steve "The Commando" Willis.
Bridges, 42, has spoken exclusively to Who magazine to set the record straight, denying that the two TV stars had an affair.
"It's developed since both of us have separated from our partners," she told Who.
"We needed some private space before we went public.
"We wanted time to explore how we both feel, and we wanted to protect our family and friends around us."
Bridges said the conversations with her husband of nine years and business partner, Bill Moore, "weren't a breeze", but they were necessary. The couple separated recently.
"Obviously the last thing you want to do is hurt someone, but I would rather be straight and have the respect of being honest with him than not," she said.
Bridges' interview follows claims this week of an affair by Willis' former long-term partner, Froso.
Froso, who asked that her surname not be published, said she learnt of the affair when Willis, 36, failed to return home after the wrap party for this season of the Ten reality weight-loss program on March 19.
"Steve and Michelle's affair was a shock to everyone," she told Woman's Day.
Froso, who has two young children with her de facto partner, said she had tried to ignore the rumours following Bridges' split with her husband.
But she started to suspect something wasn't right when Willis seemed distant after a trip with Bridges to New Zealand to shoot The Biggest Loser finale in March.
Willis and Froso ended their seven-year union when he moved out of the couple's home.
