On Sunday evening following the couple's appearance at the 60th Annual Grammy Awards, the model took to her Instagram to reveal that she and Legend will welcome a baby boy.
The 32-year-old took to her Instagram to share a photo of herself from the red carpet cradling her baby bump.
Teigen captioned the photo, "Mama and her baby boy."
The news should come as no surprise as Teigen stated that she would like her second child to be a boy.
The Cravings author dropped subtle hints about the baby's gender during the 28th Annual Screen Actors Guild Awards when she was asked about having more kids.
"A little boy is next, for sure," Teigen replied.
In an interview with PEOPLE, the second-time mom-to-be opened up about having her baby girl, Luna, through in vitro-fertilization.
The Lip Sync Battle co-host explained that she and Legend decided to do the process again so that the embryo could be made.
"We put it in, we knew what was going on. So, that was easy. But we're really excited!" Teigen stated.
In November 2017, Teigen took to her Instagram to announce that she was pregnant with her second child.
The model posted a video of herself and her daughter, Luna. In the video, Teigen points to her stomach and asks Luna, "What's in here?" Luna responds, "baby."
Revealing the gender of her second child wasn't the only thing that Teigen did on Sunday night. She also posted on Twitter a video of herself in a robe stating that she and Legend left the awards show early.

Chrissy and John Join Time's Up
Although the pair is currently preparing for their second child, they also made time to honor the gymnast who recently came forward to testify against convicted sex offender Larry Nassar.
The couple gave the Time's Up Legal Defense Fund $200,000 and called the women's effort heroic.
As previously reported, Teigen offered to pay the potential fines that McKayla Maroney would have incurred for testifying at Nassar's trial. However, the USA Gymnastics later stated that they would not fine Maroney because it encourages her and anyone else who has been abused to speak out.
