Mom Tracy Blake posted the video on our Action News Facebook page on Friday.
She says she took her son Lloyd and his 6-year-old sister Ciana to Port Richmond hoping to catch a glimpse of Stallone filming the new Rocky movie.
But it turns out, the actor gave them much more.
She captured the video showing Stallone giving little Lloyd a birthday spin to remember.
When Blake yelled out that it was Lloyd's birthday, Stallone not only ran over to swing the boy around but he also threw a few playful jabs.
She says Lloyd has been obsessed with Rocky since he was two years old.
