Prior to the question, Connelly, 67, and DiCaprio reflected on how quickly the years have gone by. "You're 49 years old. How the hell did that happen?" teased the journalist, who had often interviewed DiCaprio during his 13-year reign covering movies for MTV News.

"I have no idea," DiCaprio said in response, recalling, "We were talking about our first interview, that may have been 30 years ago."
