According to The Sun, Vicky gave birth to the couple’s son last month.
An insider told the publication: “This is wonderful news for both of them. Of course it has been an extremely tough time, but it’s lovely to have something to celebrate together.
“They’re very much united and hoping to move forwards with their new son and the rest of their family.”
The couple have been together since Jeremy split from his second wife Carla Germaine, 45, back in 2015.
The baby is his fifth child as he is also dad to Alice, 16, Ava, 14 and Henry, 10, with Carla and Harriet, 29, with his first wife Kirsty Rowley.
