Chrissy Teigen has accidentally revealed the gender of her baby to her 31.2 million Instagram followers. 

"I wanted to update you," Teigen said on her Instagram Story. "My placenta sucks. It's always been kind of the bad part of my pregnancies with Luna. With Miles, it just stopped feeding him, it stopped taking care of him. I was stealing all his food because I was getting huge but he wasn't getting big at all. He had to come out early and Luna had to come out early. I was induced both times. Anyways, it's super weak. The baby is really, really healthy and he is big!"

After realizing she has let the cat out of the bag, she seemed to attempt to reverse course, covered her mouth, and called herself stupid before continuing. 

"Anyway, so yeah it's growing beautifully. Everything is good, I'm feeling good but my placenta is really, really weak and it's causing me to really bleed a lot," Teigen added.

The news comes as the model and wife to Grammy award winner John Legend remain on two-week-long bed rest.

"I am on complete and total don't get out except to pee-pee bed rest," a 34-year-old mother of two said. "I just wanted to share that because I tell you guys everything and it's such a bummer because I had to cancel so much work and I was really excited to talk to so many different people and do these events because it would start to feel like normal life again but the timing is just s— and I apologize. I'm sorry. But I have to make baby okay."

She also urged other pregnant mothers to reach out to their doctors if facing a similar situation. With her husband of seven years, Teigen has two older children- daughter Luna Simone Stephens, 4, and son Miles Theodore Stephens, 2.
