Harris, 43, posted an adorable photo of Gideon and Harper at their first football hame on Sunday at the MetLife Stadium in East Rutherford, New Jersey, where the family rooted on the New York Giants. Fortunately for the pint-sized fans, the Giants ended up winning over the Philadelphia Eagles with a score of 28 to 23.
"First football game for these two (not quite) giants," Harris captioned a sweet snap of Gideon and Harper posing by their box seats. "Go Big Blue!"
And of course, the picture-perfect family won Halloween this year, when they paid tribute to Old Hollywood. Harper posed in a glamorous Marilyn Monroe outfit, while Gideon kept it cool as a mini James Dean.
