Chloe Madeley is pregnant with her first child with her husband James Haskell, the former rugby pro announced on Good Morning Britain.
Richard Madeley reacted to the news, as James announced they were expecting a baby girl.
James told the GMB host on Tuesday morning that he was going to be a grandfather again, as Ranvir Singh congratulated her co-host and their show guest.
Chloe's mother Judy Finnigan was shown posing alongside her daughter in a cute snap, as she revealed the baby scan - which was also shown on the show as James broke the news.
Richard had teased there was going to be something personal revealed on the show by James, who then took the moment to reveal all.
He said: "Well Richard, Chloe and I are expecting our first child. We are going to be having a little girl, and you are going to be a grandfather once again."
Richard was beaming over the news, looking to the camera with a smile on his face as Ranvir celebrated the news.
He then reacted: "We can actually see the child. Chloe sent us this, there we are her three month scan.
"That's the little girl, looks like she's reading the paper doesn't it?"
James then quipped: "Let's hope she has her mother's looks! Because if she looks anything like me we're in a spot of bother."
Richard then spoke of an image of Chloe holding a pink baby grow: "That's when she told us, that's when she gave us the news. Judi looks so happy doesn't she."
Ranvir said: "Well congratulations Richard," which he thanked her for, before congratulating his son-in-law James.
James then praised Richard as a grandfather, sharing his excitement for the family to expand.
He said: "I've seen Richard with his other grandson Kit, and he's the best grandfather in the world so I'm very, very happy."
Richard then said: "Well I've got the best grandchildren in the world."
James and Chloe both later took to Instagram to share footage of their early baby scans, as well as some snaps of Chloe's growing baby bump.
Sharing the news, James said: "Chloe and I are so excited to announce we are expecting our first child!
"From the moment I saw her and heard her little heartbeat I fell in love! Let's hope she looks like her Mum."
