Model Clair Meek, 23, had a baby boy at Crosshouse Hospital in Kilmarnock.
Last night a friend said: "Clair was determined she was going to have their baby in Scotland.
"They are the happiest people in the world. They are so thrilled and proud.
"The two of them are so in love and now they have a beautiful baby son."
James, 24 ? who plays sex fibber Jay in the hit E4 hit comedy ? proposed to Clair, of Galston, Ayrshire, last month.
