The US Biggest Loser coach has just become a mum twice over.
After finalising the adoption of a two-year-old Haitian girl only weeks ago, Jillian's girlfriend has given birth to a baby boy as well.
"It was one of those things when you put in for adoption, but she has also always wanted a baby of her own but couldn't because of health issues," an insider tells US Weekly.
An eyewitness who saw Jillian at an LA supermarket with her new toddler says the 38-year-old is a natural mum.
"Jillian was very protective of her little girl whenever she would run," the witness told US Weekly. "When they walked to the car, Jillian picked her up and gave her a big kiss on the cheek."
Naw, congratulations Jillian. Hope you manage to get some sleep, sometime!
