So far, NHS doctor Emily has said she is happy with the size of their small family.
But she admitted it’s likely they will have another child when her youngest son Theo starts school in September 2021.
Peter, 47, and his wife, 31, are parents to children Amelia, six, and Theo, three.
The Mysterious Girl singer is also dad to sons Junior and daughter Princess with ex-wife Katie Price.
And it seemed like Pete’s teenage daughter Princess and their daughter Amelia wished mom and dad would give them another brother very soon.
Emily opened up about becoming parents again in the near future in her OK! column.
She said: “Pete said the princess really wanted us to have another baby, and I think Millie [Amelia] would also say yes to another brother too.
“At the moment I’m happy with the way things are going and I’m in no rush to have another baby.
“Whenever I think it’s a good idea, I just remember how far we’ve come and how beautiful it is with the kids now. ”
Emily told fans that she and Pete are at a stage where they can do “really fun things” with the kids without “worrying about a diaper bag or diapers.”
However, the star hasn’t completely ruled it out.
Emily’s heartfelt confession comes after Pete’s 15-year-old son Junior isn’t so excited about another half-brother or sister.
Pete explained that Junior didn’t want a 17-year age gap between him and the new brother.
In his new column, Pete shared, “Bista really wants us to have another kid, but Junior is like ‘No! ”
“He says he doesn’t want to be 17 with a newborn baby – he’s not here to have such an age difference.
“But how does he think I’m going to feel?” There will be 47 years of difference. “
The singer also confessed that he and Emily kept “changing your mind every five minutes” about when it would be a good time.
