5. John Owen Lowe
Unless he was the son of the people who started the home improvement chain, there’s only one big Lowe that comes to mind: Rob. When Rob Lowe met Sheryl Berkoff he was a partying mess, but they married and he learned to be monogamous. John Owen was the first product of their love, but they have another son, Matthew. As John ages, he’s taken an interest in the family business, acting in a few TV series, including his Dad’s show The Grinder.
