At the time they dated he was 29 and she was 58. In September 2020 he earned headlines after being revealed as actress Rebel Wilson's boyfriend. Once again he is dating an older woman. Rebel is 11 years older than Jacob. Jacob's great-great-grandfather, Adolphus Busch, co-founded the Anheuser-Busch brewery back in 1852.
Jacob studied International Business and Entrepreneurship at St. Louis University. He is said to be involved with the product Party Pass Breathalyzer from Runaway Productions. He is a West Coast ambassador of The Peter W. Busch Foundation to benefit The Busch Wildlife Sanctuary, the Cystic Fibrosis Foundation, and The Boys and Girls Club. Busch also works with Mission Save Her to fight sexual and human trafficking.
In 2016 Jacob co-founded "Barrels & Sons Brewery". His two co-founders come from equally-famous restaurant and alcohol families. Co-founder Carlos Mandavi is the grandson of legendary winemaker Robert Mondavi. Co-founder Elliott Taylor is the son of restaurateur Ronald Lee Taylor. Their brewery is located on 300-acres in Saint Helena, California, just north of Napa.
