Ladies and gents, here's your new host of The Tonight Show.

Jimmy Fallon made his official and highly anticipated debut as the star of The Tonight Show on Monday evening in New York City.

"Welcome to the Tonight Show!" Fallon told the hyped-up audience. "This is the first Tonight Show broadcast from New York in over 40 years. I'm Jimmy Fallon and I'll be your host...for now," he quipped.

He continued: "Of course, I wouldn't be here tonight if it weren't for the previous Tonight Show hosts, so I want to say 'thank you' to Steve Allen, Jack Paar, Johnny Carson, Jay Leno, Conan O'Brien and Jay Leno."
