Howard Stern celebrated his 60th birthday in a very big way on Friday night, inviting everyone from David Letterman, Jimmy Kimmel and Jimmy Fallon to Adam Levine, Joan Rivers  and Robert Downey Jr. to a big blowout at New York's Hammerstein Ballroom.

Some of the birthday wishes came from surprising corners: Rosie O'Donnell  sang about being a target for the legendary shock jock, and Longtime Stern nemesis Kathie Lee Gifford  taped a video greeting. There was the Dixie Chicks' Natalie Maines teaming up with Sarah Silverman on a hilarious Howard Stern Show tribute song, the Foo Fighters Dave Grohl serenading Howard with "My Hero," and Steven Tyler and Slash performing "Dream On" together. (Grohl joined Slash and Tyler for "Walk This Way."

Joan Rivers joined in roasting Stern, joking "If your face were a car, if would be Paul Walker's Porsche." When the audience groaned, Rivers fired back, "What do I care? I'm 80-years-old!"

Our favorite part of the show, however, was when actor Ryan Phillippe paid due tribute to Stern sidekick Robin Quivers by giving her a shirtless lap dance.
