The birth of a Legend: Chrissy Teigen announces second baby's arrival

Model Chrissy Teigen, 32, and singer John Legend, 39, have announced the arrival of their baby boy, who comes ahead of schedule.

The cookbook author used Twitter to reveal that their son, and second child, had arrived late on Wednesday, US time.

No other details have been provided by the parents, who already have a two-year-old daughter, Luna May.

The baby, due in June, came one week after Teigen declared she was "over" being pregnant.

A fan commented that it seemed as though Teigen had been pregnant for "three years," and she reportedly agreed, posting: "It feels worse for me because with IVF you know *so* early. I mean I knew I was pregnant at 11 days in. Crazy."

Teigen had postnatal depression after the birth of her daughter, and revealed at a Los Angeles careers conference for women in February that she still held some fears about experiencing it again.

"Do I worry about it with this little boy? I do," she reportedly told the conference.

"But I also know that I feel like when it does happen, if it does, I’m so ready for it.

"I have the perfect people around me for it. That’s why I really stand for a good core group of people around you."
