Modern family: Jillian Michaels and her lesbian partner step out with their baby boy and adopted daughter



Former Biggest Loser trainer Jillian Michaels enjoyed a double dose of happiness in May after welcoming two children into her home in two weeks.



The 38-year-old took home a two-year-old girl, Lukensia, from Haiti on May 12 following a lengthy adoption process.



And then it has emerged that her secret lesbian partner Heidi Rhoades gave birth to a son Phoenix just two weeks earlier.

Two months in and the modern family are doing just fine, as they were pictured hitting up the Malibu Farmers Market with a male friend.

Looking casual in jeans and jumper paired with flip flops, Jillian kept her arms free to gather groceries while Heidi carried little Phoenix and Lukensia got a ride with a male friend.

Jillian, who revealed she was bisexual in 2011, has been quietly dating Rhoades, 31, for three years and says she is thrilled to watch her family grow.

'Seeing my two kids together is a magical feeling,' she tells People magazine. 'Motherhood changes your DNA. My kids are now an integral part of who I am.'

But the rapid expansion certainly came as a surprise, with Rhodes adding: 'It's not the way we had planned it! But that's how our life works. It's always big. It could never be something like one child at a time.'

Jillian told the publication that she hadn't been to the gym for two weeks and had a new appreciation for the many mothers she coached.

'I have yet to figure out how to take care of myself right now.'

'Telling moms "You need to put yourself first"?' she says, rolling her eyes. 'It's impossible to put yourself first when your a mom.'

'You have to sacrifice and grow up.'

Jillian left The Biggest Loser last year to focus on becoming a mother, and was replaced by Anna Kournikova.
