BAD GRANDPA producer JARROD BROM is heading for divorce, two years after he allowed the movie's star, prankster Johnny Knoxville, to trash his wedding and use the footage in the 2013 comedy. The Jackass daredevil crashed into a Champagne tower and destroyed the couple's cake during their nuptials - and now Brom's wife, Kimberly Peeler, has filed to end their marriage, reports TMZ.com.
