The radio personality, who turns 40 this month, has been a little more vocal about settling down than he has in the past, calling his upcoming age a "turning point number."

"I look at what my mom and dad have had for 40-plus years -- a fantastic relationship and great marriage," he told People. Speaking about his upcoming birthday, he said, "[Hitting 40] is a turning point number where you go, 'Wait, you've got to grow up a little bit.'"
