Chrissy Teigen has given birth to a baby boy.

The 'Sports Illustrated' model took to Twitter to announce her and husband John Legend's second child had arrived in the world. Alongside baby bottle emojis, she wrote on Twitter: "Somebody’s herrrrrrre! (sic)"

The message was also retweeted by John onto his own Twitter account.

Just a few days ago, Chrissy admitted she was "over" being pregnant as she was just desperate to meet her son, especially as she has known from day 11 that she was pregnant as she underwent IVF treatment.

Venting her frustration on Twitter, she shared: "Happy pregnant Chrissy is gone. meet OVER IT Chrissy. Wanna hold my boy let's do thisssssss ... It feels worse for me because with IVF you know *so* early. I mean I knew I was pregnant at 11 days in. Crazy. (sic)"

And Chrissy had previously admitted her second pregnancy has been a lot harder than the first time around.

She said: "Your second pregnancy is harder because you have a kid already."

Whilst John added: "You have to divide your energy between raising a kid and carrying one as well."

However, the couple have also been concerned about how well their daughter Luna, two, would adapt to having a sibling.

John said: "Luna's gonna be an issue. I think she'll probably have some growing pains because she's currently running the house right now.

"She's used to being the centre of everything right now so we'll see how she adjusts to sharing the spotlight."
