Jake Gyllenhaal [1] is a busy, busy man. Aside from promoting his upcoming movie Life [2], he's also playing pointillist painter Georges Seurat in the Broadway musical Sunday in the Park with George. The talented actor stopped by The Tonight Show Starring Jimmy Fallon [3] on Monday, and aside from bonding with the host over their mutual love for Ferris Bueller's Day Off, he gave us a sneak peek at his tricky singing for his show. Let's just say, the tongue twister lyrics and his gorgeous voice [4] will leave you breathless. You can catch it at the 2:35 mark.
