The claret and blue hero answered his critics by scoring the decisive goal in the 1-0 win at St Andrews.
Tina was in the Villa Park crowd when the groundless chant was repeated on Monday, as Villa drew 1-1 with Manchester City.
She told the Sunday Mercury: "They started to sing that at the game as I was sitting behind the goal.
"I felt like turning around and saying: Do you know who I am? but I stopped myself.
"I was too interested in watching Gabby to take too much notice anyway.
"But I couldn't resist shouting: Come on son!"
