• e-mail

World champion skier Bode Miller has shared the first photographs of his new family of four after welcoming a baby girl on Saturday.

Bode and his wife, volleyball player Morgan Beck Miller, left little to the imagination in pictures posted Sunday that show the couple naked, along with what appears to be the newborn's umbilical cord still intact.

Regardless, the joy at the arrival of their second child together was palpable in the Instagram photos, and fans rushed to offer their congratulations.

On Saturday, Morgan announced: 'Our baby girl made her way earthside (sic) this morning ... 7 lbs 4 oz 20.5" #grateful for another successful home birth.'

The baby girl, whose name has not yet been released, is Bode's fourth child and the second with Morgan, who gave birth to their son Nash Skan Miller in May 2015

The couple were the picture of bliss as Bode cradled his son in his arms and appeared to introduce him to their newborn, who was resting on top of Morgan's naked body shortly after a home birth.

Bode wrote in the caption: 'It was an amazing day for the Miller family yesterday as we welcomed our baby girl.' 

His wife also posted another heartwarming image of a shirtless Bode cradling both his kids in each arm as she gushed in the caption: '#doesntgetanysweeter' 

Morgan has shared a number of images throughout her pregnancy, along with snapshots of her Olympian husband spending time with all of his children together.

The 39-year-old Alpine skiing champion already has an eight-year-old daughter, Neesyn Dacey, with an ex-girlfriend, Chanel Johnson, and a three-year-old son, Sam, with another former flame, Sara McKenna - and he has made headlines as much for his skills on the slopes as he has for his child custody disputes.

His custody battle with Sara had been so bitter that he refuses to call their son Sam, instead opting for 'Nate'. Bode chose the name to honor his brother who died of a seizure at the age of 29 in 2013.

Sara, a former Marine he met through a matchmaking service, fell pregnant with his child three months into their relationship and Bode said he did not want to raise the boy with her.

At seven months pregnant, Sara moved from California to New York to attend Columbia University on the G.I. Bill, while he married Morgan.

Sara said she told him of her plans in a text message but he never responded.

But two weeks after Sam was born in February 2013, Bode filed for custody in California and she temporarily lost custody of him, Sara recounted in an essay forCosmopolitan. 

In September 2013, a judge gave Bode full custody of Sam, calling Sara's move to New York 'irresponsible' and 'irreprehensible', but she ultimately won back custody of her son.

The details of the custody deal finalized at the end of 2014 have not been made public.

'Neither of us got exactly what we wanted, but Sam got what he needed and that's what's most important to me,' Sara, 28, said at the time.

Bode has also fought Dacey's mother, who has remarried and now goes by the name Chanel Pugh, for joint and physical custody of their daughter, as well as child support payments.

He and Morgan regularly share images of his oldest two children across their social media pages, where they call Sam 'Nate'.

Bode and Morgan, who met in 2012 just months after he began dating Sara, were married in October 2012.

Their baby boy, born in 2015, was the first child for Morgan.

In 2013, she suffered a miscarriage with Bode's child just a month before Sam was born.

Two years ago, after Morgan announced she was pregnant, Sara wrote online: 'I hope he and his wife, Morgan, have a healthy and beautiful baby and grow with their new parental roles.

'I'm happy [Sam] will have another sibling. He is so loving and sweet, and will be an amazing big brother just like he is a great little brother.' 

But she added that she was pursuing legal action against Morgan, who had falsely suggested online that Sara only fell pregnant with Bode's son after she fished a condom out of the trash.

Bode, a native of New Hampshire, now lives in California with his wife. In September he asked a federal judge to void his contract with a former sponsor who is trying to ban him from making a comeback in the competitive circuit.

He filed a lawsuit against his former sponsor Head USA Inc in a California court, who has threatened him with legal action if he returns to competitive skiing.

The skier wants to return to the slopes for the 2016/2017 World Cup and Championship season - sponsored by ski product manufacturer Bomber - in hopes of securing his family’s financial future.
