The two pals were all cuddled up while sitting in the stands, which they have done several times before.
When one commenter wrote, “Is the boy next to you your son or why do you hang around with him?”
Beckinsale replied, “He is my son, yes. I kept him in the cellar for 29 years but now I feel I should take him out on jaunts.”
This isn’t the first time Beckinsale has gotten cheeky when online shade has been thrown her way.
