Rob Lowe says he had simple advice for his 29-year-old son when he told him he wanted to be an actor. He told Fox News Digital his advice to his son, John Owen Lowe, was to "just be a content creator." Lowe added that John recently sold a new show to Apple TV+."And the irony is now that's really, I'm so proud of him creating this new show, and that's the thing I think today, as opposed to when I came up, there's no excuse to not make your own stuff today," said "The Floor" host. He added, "It's so much easier to do, and I'm glad he's doing that. That was really the big piece of advice I gave him."
