Chrissy Teigen - who is pregnant with her second child - wants to have three children "back to back to back" and will then focus on getting "hot".

The 32-year-old model already has daughter Luna, 23 months, with husband John Legend and is currently five months pregnant with their second baby, but she's keen to conceive again quite quickly after their son is born - and then she'll focus on getting "hot".

She said: "I think I do want to have another baby after this and then get hot.

"I just want to go babies, back to back to back, but then I think maybe I want to have my 30s, really live in my 30s and not just be pregnant throughout them."

The 'Lip Sync Battle' star is delighted her 39-year-old husband "truly loves" her pregnant figure.

She told Us Weekly magazine: "I have a husband who truly loves the whole experience.

"He holds my belly at night, sings to it, wants to be there for me. I'm really lucky because some men start to look at you like a tool, I've heard, so I've been scared and don't let that happen to me! But it hasn't and it's really good."

Though Chrissy and the 'All of Me Singer' know they're expecting a boy, they are really struggling to choose a name for their son.

She admitted: "We are doing horribly. We didn't even pick out Luna's name until three days in the hospital when they told me I'd have to go down to the courthouse and I didn't want to go down there after I had just given birth.

"But it's tough for boy names. It's harder. I have an arsenal of girl names, but between John and I, we feel that we know somebody with every name that we try and pick out."

But the couple will be opting for a "traditional" moniker for the tot.

She added: "I want to wait to see him before we give him a name. I'm not mad at the name J.J. for John Jr. -- I like traditional names. It's not going to be a wild name. Ronald is a cute name in our family. His brother, my brother, my dad ... 

"I like boy names on girls. When I think of a boy name, I always just think it's better for a girl."
