Legend likes to sing and dance with Luna, be it in their kitchen, the game room, or just on a fun jaunt throughout the house.
Teigen took to social media on Thursday to make the announcement. "Somebody's herrrrrre!" Teigen tweeted Wednesday, along with a baby bottle and high-five smiley emoji.
Although Chrissy felt like she was with child for all the days of her life, what she knows for sure is that she and John want to have more.
Teigen has been open about her struggles with fertility for some time now and frequently discusses IVF and how she feels throughout her pregnancies. Meet OVER IT Chrissy.Wanna hold my baby boy let's do thissssssss...More news: Pep Guardiola: LMA manager of the year
"She knows to call it a baby, but I don't know if she's clarified what that really means to her."
The pair are also parents to daughter Luna, who was born two years ago.
At one point Teigen complained that during her pregnancy she had put on weight in places she didn't expect - including her nose. "I think she'll probably have some growing pains because she's currently running the house right now". "A boy. So. Yeah", she wrote on Twitter, referencing the couple's use of in vitro fertilization.
We have a feeling Luna will adjust just fine!
Chrissy and John met on the set of his Stereo music video in 2008 and dated for four years before he proposed in 2011.
