Chrissy Teigen and John Legend have welcomed a baby boy.

The model, 32, announced the happy news on Wednesday evening, but is yet to reveal her son's name or share a snap of the no doubt adorable newborn.

She tweeted, "Somebody’s herrrrrrre," along with two baby bottle emojis and two cuddle emojis.

Chrissy and John, who are already parents to daughter Luna, revealed they were expecting a baby boy back in January.

Sharing a baby scan on Instagram following the Grammy Awards, Chrissy wrote: "Mama and her baby boy."

They first announced they were expecting their second child last November, and roped in Luna to reveal the happy news in a sweet video as she stroked her mum's tummy.

At the end of April, Chrissy was thrown a lavish baby shower that was attended by the likes of Kim Kardashian, Kanye West and Kris Jenner.

Guests feasted on milkshakes and burgers from Shake Shack as well as mountains of cake, while John provided the musical entertainment behind the piano.

Chrissy and singer John welcomed their daughter in April 2016.

The star later opened up about her struggles with post-natal depression following the birth.

The model revealed she had a downward spiral, and barely left the house as a new mum, battling emotional outbursts that worried her family and friends.

Penning an honest article for Glamour magazine, she explained how she suffered mood swings and lost her appetite, and said even getting out of bed was painful as she doubted whether she should be a parent.

"One thing that really got me was just how short I was with people... I couldn’t figure out why I was so unhappy," she wrote.

"I blamed it on being tired and possibly growing out of the role: 'Maybe I’m just not a goofy person anymore. Maybe I’m just supposed to be a mom...' "

Chrissy said she went to see her doctor, and took antidepressants after being diagnosed with anxiety and postpartum depression - and said she was also considering therapy.
