Seattle Seahawks QB Russell Wilson reads his mom's Mother's Day message not knowing that she's standing close by.

He says, "Dear Mama, Happy Mother's Day. I want to thank you for always being there as a positive force in my life. You are the definition of a perfect woman  - a giver, nurturer, caretaker, who exudes grace at all times - no matter what obstacles life throws at you. What a lucky, no I should say blessed guy I am, to have been born to a woman as strong, generous and loving as you."

Watch his reaction and the love of a son for his mother.
