Just a month after Simpson filed for divorce from her rocker husband after 2½ years of marriage in 2011, the former couple were spotted with 4-year-old son Bronx holding hands on a family outing that set the tone for an amicable relationship. "We remain friends and deeply committed and loving parents to our son," they said at the time of the split, and that was a promise they made good on when they threw Bronx a birthday party in 2012.
