WAGNER and his 21 year-old girlfriend have welcomed their “perfect” baby boy into the world.

Lydia Longville gave birth to Leon Wagner Fiuza-Carrilho at 1.57am today.

The singer announced the news on twitter, with Lydia later adding the newborn was just like Wagner.

The couple, who have been together for two years, first met after Wagner performed at The River Rooms in Stourbridge following his stint on the X Factor.

The couple, who have a 36 year age gap, announced they were expecting a baby boy in the summer and also revealed they had chosen the name Leon as they wanted a strong name for their son.

Speaking to the News at the time, Wagner and Lydia said they had picked Leon as it means lion in Spanish, so he would be their “little lion Wagner.”

The baby is a second son for Wagner, who already has a child from a previous relationship.
