biography.

      Jack Finnegan Gilinsky is a 20 year old singer born in Omaha, Nebraska. Jack was born September 10, 1996. Katherine Finnegan-Gilinsky and David Gilinsky are the parents of Jack and his sisters Laura & Molly Gilinsky, who are 21 and 22 years old. Jack is an American pop-rap duo singer with his best friend, Jack Johnson, which together are the popular Jack & Jack duo. Before he was famous, Gilinsky started out on an app called "Vine" one summer when everything went boring. Him and Jack Johnson began making vines and becoming and more famous with each view they got. Eventually, in 2014, Jack and Jack released their first single "Wild Life" which ranked #87 in the billboards, also winning a Most Popular Viner award in 2014 and a Top Social Climber award in 2015. 

      Even before Jack thought about Vine and fame, him and his friends created comedy videos to keep people entertained and happy, hoping to someday become big and make a difference in the world. After Jack & Jack released more music and tours, and after years of trying to grow larger, they continued to be an inspiration for people, and to help accomplish that, Jack Gilinsky published a book in mid-September called "You Don't Know Jacks" with the help of his best friend, Jack Johnson.
