Grant is said to be “absolutely thrilled” with the baby girl, who was born in October, and although he is not with the mother – who is unknown – he is “beaming” about having a child.
A source told US Magazine: “He’s going to be a great dad! He’s beaming about his daughter. He’s not with the mum anymore but he’s absolutely thrilled.”
Grant was last linked with Chinese actress Tinglan Hong, but is it not known if she is the mother.
