Rob Lowe has been a Hollywood hunk for over three decades now, though the actor fears he's starting to face some competition from his handsome sons, Matthew, 22, and John, 20.
"Listen, I'm fully embracing the old man moniker," Lowe joked with ET at his Hollywood Walk of Fame ceremony on Wednesday, where he was joined by both boys, as well as wife Sheryl. "They're hot, they're young, they're on it. I'm old. I'm on my way out, everybody knows it."
"I was chosen last for my family's Turkey Bowl this year so the insults just keep on coming," the 51-year-old actor added with a smile. "Which is why today is so nice."
John even guest starred on his dad's sitcom, The Grinder, earlier this year.
"Here I thought I avoided all the pitfalls of raising actors," Lowe told ET's Ashlan Cousteau back in September. "[John] is at Stanford and we're like, 'We did it! We got him into a big school!' He was one of the leading interns in stem cell research. Now he's going to be wearing makeup for a living."
There's no hard feelings from Lowe, though, who says that, for him, "Dad" is the role of a lifetime.
"No matter who you are or where you are in your career, your number one job is to raise your family the best way you know how," he said. "I've always felt that way and I've loved every minute of it. I do feel like that's my most satisfying accomplishment."
