Joe Jonas thinks Chrissy Teigen and John Legend will have "the most beautiful child."
Chrissy Teigen and John Legend
The 26-year-old musician, who is close friends with the couple, couldn't be happier they're expecting a baby after struggling with infertility issues for several years.
He said: "She's the funniest girl. And he nurtures and cares for everything around him. They're going to have the most beautiful child."
The 29-year-old model is "so excited" to be four months pregnant even though she is experiencing some negative symptoms.
A source told PEOPLE magazine: "She's had morning sickness pretty much every day. But she is so ecstatic."
John recently teamed up with Meghan Trainor to record the track 'Like I'm Gonna Lose You,' and the 21-year-old singer also has no doubt he'll be a great parent.
She said: "John will be the best dad ever! They'll laugh and dance and sing."
The couple announced the happy news just a few weeks after Chrissy was reduced to tears when she opened up about her struggles to conceive on her new talk show 'The FABLife'.
Although she found it tough revealing her heartache to the world, she later admitted she's wanted to speak out about her problems and use of IVF for a while now.
She said: "I just wanted to talk about it for so long ... It didn't feel right to tweet, 'Ugh, doing my IVF shots again.' "
