The personal trainer behind celebrity killer bodies including Gwyneth Paltrow, Jennifer Lopez and Madonna has apologised for her comment that women use their pregnancies as "an excuse to let their bodies go".
The new mum, who welcomed her daughter Penelope just a few months ago, has faced a backlash following her comments and now she's told Good Morning America that she's "so mortified".
She said: "I am so mortified, it sounds so bad when it comes back like that. It's not what I meant.
"I've spent 14 years very focused creating all of this original content, testing on women to make sure I can give women something that really works so they can be their most empowered self," she said.
"So the last thing I would do is judge a woman, especially after children."
Tracy, who has created a brand from her work with celebrities, was talking to DuJour for its September issue where she posed with her six-week-old daughter.

The personal trainer claims to have gained 30lbs during her pregnancy, but when she had been pregnant in 1998, she put on double the amount because she ate unhealthy food like hotdogs and milkshakes.
"A lot of women use pregnancy as an excuse to let their bodies go, and that’s the worst thing," she said. "I feel like I’ve lived an entire lifetime since then."
Tracy, 37, also claimed that many of her clients blamed their out-of-shape bodies on having children.
"I’ve seen so many women who come to me right after [having children] with disaster bodies that have gone through hell, or they come to me years later and say, 'Oh, my body is like this because I had three kids,'" she said.
During her interview on live TV, she tried to explain her controversial comments as she said: "Pregnancy is difficult and every pregnancy is completely unique. We crave a lot. I think in today's society where we have all of this pressure to look a certain way, I feel like they turn to diet a lot because that's what works for them because fitness routines usually let them down.
"So when they do get pregnant it's like 'Oh my gosh!' It's not just like, 'I'm going to let my body go for this pregnancy,' It's also, 'I can eat all the things that I never let myself eat.'
"I see people that come to me after pregnancy and they didn't need to necessarily gain that much weight."
Do you think Tracy's comments have been taken too seriously? Or do you think she's harsh on mums?
