Heidi Roadhes, the partner of "Biggest Loser" trainer Jillian Michaels delivered the couple's son on May 3.

Michaels confirmed the news today on her Twitter.

"I'm really happy to share that my daughter is finally home & my son was born on 5/3," Michaels Tweeted Wednesday.

Their son Phoenix was born in Los Angeles and joined the family the same week their adopted daughter Lukensia came home, reports People Magazine.

"We're swimming in babies over here," Michaels, 38 told People magazine.

Michaels had to wait for two years until her daughter's adoption process was finished. Lukensia is from Haiti and is 2 years old.

Michales was a personal trainer on the popular reality show until the eleventh season of The Biggest Loser in May 2011.

In a controversial piece in 2010, the Los Angeles Times claimed Michaels "is not actually a real fitness trainer — she's an actress playing the role of fitness trainer on TV and in a line of popular DVDs." The story allegedly said had let many of her fitness certifications lapse.

Michaels denied the accusations and threaten to sue the paper for defamation. Shortly after, the paper published a correction citing her up to date certifications and no legal action was taken.
