Jillian Michaels and partner Heidi Rhoades 'swimming in babies' as they welcome two to their home

Jillian Michaels was used to having her hands full on "The Biggest Loser," but now she's taking on an entirely new challenge - motherhood.

Michaels and partner Heidi Rhoades have recently welcomed two new babies to their Los Angeles-area home. Jillian recently brought home 2-year-old daughter Lukensia from Haiti after a lengthy adoption process, while Rhoades gave birth to their newborn son Phoenix on May 3 - and it all coincidentally happened in the same week.

"We're swimming in babies over here," Michaels tells People. "I don't even answer email. I don't have time to care about anything else. I want to be really present and enjoy all the nuances of their growth and development. I don't want to rush any of it."

Michaels writes on Facebook, "I am really happy to finally share with you that I have brought my daughter home AND I have a newborn son ... Thanks for sharing this long journey with me. I am so grateful."

Congratulations to Jillian and Heidi (whom Jillian affectionately calls "Mouse" on Facebook)!
