'Arrow's' Stephen Amell and Cassandra Jean welcome baby girlAdd to Favorites | Arrow
He is referring to the fact that on Wednesday nights on the CW, viewers get a double dose of Amell, with Stephen in "Arrow" at 8 p.m. ET/PT and his cousin Robbie Amell on "The Tomorrow People" at 9 p.m. ET/PT.
Amell and Jean were married in December 2012. Jean is an actress and model who famously quit "America's Next Top Model" Cycle 5 when she refused to cut her hair even shorter than had already been done in her makeover.
UPDATE: In a statement to Just Jared, a rep for the actor says, "Mavi Alexandra Jean Amell was born on Tuesday afternoon (October 15). Everyone is happy and healthy."
