Jillian Michaels, new mom to two, still a hot bod Jillian Michaels, new mother to two beautiful children, once reportedly told a magazine that she would adopt rather than "do that to my body." "I can't handle doing that to my body," the former butt-kicking "Biggest Loser" personal trainer was quoted as saying by Women's Health in 2010. Since then, she has adopted daughter Lukensia, 2, from Haiti. And her partner, Heidi Rhoades, gave birth to son Phoenix on May 3. Michaels has also opened up about medical conditions that affect reproductive health. She told Redbook she had PCOS (polycystic ovary syndrome), which is characterized by the formation of small cysts on the ovaries. To People, she said she suffered endometriosis as a teen. According to numerous health sites, either one of the conditions can cause infertility as well as problems during pregnancy. In People, she said she didn't think that, as an adult, she would even want children. Turns out she did, and now Michaels is bubbling over with excitement. The fact that Michaels had a partner came as a surprise to many. She had told Redbook that she was "adopting as a single parent," although she added that she was seeing someone. Now, she and Rhoades and their two children are a big, happy four-member crew. She tweeted Thursday: "I'm really happy to share that my daughter is finally home & my son was born on 5/3." Later, she wrote: "I wish I could respond to every kind message I'm receiving from you all. I'm seeing and we are reading them.
