Jimmy Fallon and Drew Barrymore go way back. The two have been friends for years, and Drew is actually responsible for Jimmy and Nancy Juvonen's 12-year marriage. Jimmy and Nancy first met through the actress when Nancy visited the Saturday Night Live set, though it wasn't until Drew and Jimmy starred in 2005's Fever Pitch together that a romance blossomed between Jimmy and Nancy. In fact, Drew's daughters, Olive and Frankie, are also close with Jimmy's daughters, Winnie and Frances, and they've known each other since they were babies.

From starring in Fever Pitch and Whip It together to their hilarious late-night show appearances, it's clear that Drew and Jimmy's friendship is one of a kind. We wonder if Jimmy has invited Drew to appear on his at-home Tonight Show series yet? Ahead, take a look at some of their cutest moments together.
