The 30-year-old FABLife host shared a video via Snapchat on Tuesday, showing off her sizable baby bump, and exclaiming, "My belly is bigger than my butt!"
Earlier that day, Teigen spoke about her body during on a new episode of her panel talk show FABLife, where she opened up on her ever-increasing cup size.
"I'm still second trimester and I have -- I don't even know. I think I'm rocking a 40 double D now," Teigen revealed to her co-host Joe Zee while discussing tricks women can use to increase their bra size. "I have no idea how, but Joe, let's double them!"
Looking through a collection of bras, Zee pulled out a black lace option, but Teigen was shocked at how small it was compared to her own bras.
"That's like a nipple cover for me right now by the way," she joked. "My nipples are all sorts of weird."
Teigen added that she's really happy she "showed them off so much on Instagram, because I'll never see them that way again."
