Miley Cyrus: Backstage with Jimmy Kimmel!

Miley Cyrus rubs shoulders with late-night talk show host Jimmy Kimmel backstage during rehearsals for the 2008 American Music Awards at the Nokia Theatre on Saturday in Los Angeles.

Kimmel, who will host the AMAs tonight, may have something up his sleeve for Miley, whose birthday is today. Asked if anyone should worry about being fun of at the show, he said, “It’s Miley Cyrus‘s birthday that night…”

HAPPY BIRTHDAY, SMILEY!!!
