Wayne Rooney's wife Coleen broke the internet last week after sharing the first photo of her newborn son Cass Mac Rooney. The 31-year-old Coleen broke the internet again this week by posting the cutest photo ever on her Instagram page.

Cass Mac is Everton forward Wayne Rooney and Coleen's fourth child together. Although not confirmed yet, the little member was possibly born on Valentine's Day 2018.

In the recent photo posted by Coleen, the star couple's eldest son Kai Rooney is seen kissing his lil bro Cass Mac. It has already become one of the most viral photos of the week.

The 32-year-old veteran English forward, who married Coleen when he was at Manchester United a decade back, also welcomed the newest member of the family in his own style. 

"5-a-side team complete! Welcome to the world Cass," Rooney, who has retired from international football duties, captioned the photo.
