Tom Brady's Kids -- LET'S GO DADDY!

C'mon, this is adorable ... even if you're a Colts fan.

With the New England Patriots gearing up to take on Indianapolis for the AFC championship later today, Tom Brady's kids are doing their part to cheer on their dad.

Tom's three children -- John, Benny and Vivian -- threw on their #12 jerseys and made a sign for Tom that read, "Go Patriots! Love you Daddy!"

Tom's wife Gisele also posted a note that read, "We are ready!!"

Sidenote -- look at the view from Brady's house. Ridiculous.
