Ice-T
Tracy Lauren Marrow, most widely known by his stage name Ice-T, is an American rapper and actor, known mostly for his performance in Law & Order: Special Victims Unit. Ice-T became a father at the age of 18 when his high school girlfriend gave birth to their daughter. The two completed their last year of high school while raising their baby girl.

Sixteen years later, in 1992, Ice-T welcomed to the world his second son, Ice Tracy Marrow, Jr. He had another family celebration later that year, when his daughter gave birth to her first son, making the actor a grandfather at the age of 34. This means that his son and his grandson are at the same age.
