Coleen Rooney has shared the first picture of her newborn baby boy on Instagram, and it's absolutely adorable.
She wrote: "So Happy to welcome our Baby Boy .... Cass Mac Rooney into the world weighing a healthy 8lb 10oz. He is beautiful đź’™".
It didn't go unnoticed by fans that Coleen had strayed from her Kardashian-esque tradition of giving her sons names beginning with 'K'.
Coleen and Wayne Rooney are already parents to Kai,8, Klay, 4, and two-year-old Kit.
After she announced it on Twitter, one fan wrote: "Omg beautiful name.. you should of spelt it kass to stick with the tradition. Congratulations (sic)."
Other followers joked Coleen could start her own football team after giving birth to another boy.
