Chrissy Teigen and John Legend are expecting their second child.

The ‘Sports Illustrated’ star and the ‘All Of Me’ hitmaker have taken to Instagram to reveal they are adding to their family.

In a video posted to Instagram, Chrissy points at her stomach and asks her daughter: “Luna, what’s in here?” to which the little girl replies, “Baby!”

The couple – who already have 19-month-old daughter Luna – have made no secret of the fact they want more kids.

Chrissy had previously revealed she would love to be “pregnant for the rest of her life”.

She shared: “I feel good, I feel good, we’re still trying … I’m going for I mean hopefully in the next few years because for me I really want to just knock ’em out. That’s my dream, I want to just be pregnant kind of for the rest of my life. Not for the rest of my life, but the rest of my fertile life. So we’ll see.”

Whilst John added: “We want more, we’ll hopefully have another one in the near future. We’re working on it.”

And Chrissy “cannot wait” to have a bigger family as she loves being a mother to Luna.

She shared: “I probably think about it more than anybody. I cannot wait to have the biggest family. Everybody is curious. They’re like, ‘When are you going to do it? When are you going to do it? When’s the process going to start?’

“It’s so fun absorbing baby Luna right now. I think I’m enjoying my time absorbing and seeing everything – all her new little steps and new moments – and being there for them…

“Every day it’s something new with her. More than anything, I love seeing her little palette. She will eat anything and everything. I just think it’s so fascinating. You give her the whisk and she knows exactly what to do the second you teach her. It’s really cute.”
