Lady Gaga, Lindsay Lohan Surprise Fallon on “Tonight Show” Debut

Jimmy Fallon got his “Tonight Show” off to a great start, with a little help from his friends.

The late night host made a joke about how his friend who bet him he’d never host the iconic NBC talker owed him $100, and surprisingly, he was able to collect.

More than a dozen stars turned out for the occasion, showering Jimmy with $100 bills. Along with Lindsay Lohan and Lady Gaga were a range of celebrities that also included Kim Kardashian, Robert De Niro, Tina Fey, Mariah Carey, Joan Rivers and many more.

After Gaga, who will perform on the show later in the week, whispered something mysterious in Jimmy’s ear, his old frenemy Stephen Colbert showed up.

Colbert, who hosts Comedy Central’s “The Colbert Report” in the 11:30 slot, showered his friend with what appeared to be $100 in loose change.

What’s more, he paraphrased from that now-iconic “The O.C.” moment, telling Jimmy, “Welcome to 11:30, b****.”
