Howard Stern, everyone’s favorite radio host, celebrated his 60th birthday yesterday with a slew of friends and celebrities at a party hosted by SiriusXM.

“Howard Stern’s Birthday Bash,” presented by Sirius, was held Friday night at NYC’s Hammerstein Ballroom.

Sirius also used the opportunity to host a special four-hour radio show live from the event.

Hundreds of Stern’s friends and fellow celebs were present to see Stern turn 60, including his model wife, 41-year-old Beth Ostrosky Stern.

Tons of famous figures walked the red carpet at the Hammerstein before entering the blinged-out ballroom.

Some of the guests who made the list included Girls creator Lena Dunham, television personalities David Letterman and Jimmy Kimmell, Jon Bon Jovi, actor-couple Donnie Wahlberg and Jenny McCarthy, comedienne Whitney Cummings, Rosie O’Donnell, Aerosmith’s Steven Tyler, New Jersey Governor Chris Christie. Maroon 5’s Adam Levine was also at the party as a guest, as well as a performer.

One other sunny face was also in attendance: Patricia “Tan Mom” Krentcil.

According to USA Today, as they talked to actor David Spade, who was in the midst of questioning just why “Tan Mom” was there, the sunkissed Krentcil pulled up her black dress and gave Stern a second-floor view of her bikini bottoms, yelling to another guest, “Don’t judge me, you motherf*****!”

Jimmy Kimmell was the host of the night, appearing on the stage next to a desk where Stern and his longtime radio co-host, Robin Quivers, sat to observe the party.

Kimmell took the opportunity to “roast” Stern somewhat, telling the audience, “Howard Stern did to radio what Picasso did to visual art. He was the first. He is the best. And, we know exactly how long this man’s penis is! He is the most self-absorbed person on the planet and we can’t get enough of him.”

The radio show/party host, Kimmell, also described the uniqueness of the crowd, telling attendees to note their fellow guests in attendance and, “…look around the room at the variety of people [here]. Drunks, whores, stock brokers, stutterers, Oscar-winners, retarded people…”

When asked how he felt about turning 60, Stern replied, “I’m sort of in denial, I kind of go, ‘Wow, I don’t look 60, I look good! And then I see a picture of myself and go, Uhhh. But I feel good. I’ve been working out a bit.'”

Friend and co-host, Robin Quivers, said that Stern has a “six-pack now,” and wife Beth Ostrosky Stern related that the star has lost “30 pounds in the last six months.”

According to Howard, though, a fear of “getting old” isn’t what prompted his weight loss, but rather, that he was “getting a little too heavy” and had to “…nip it in the bud.”

Stern says that he was “overwhelmed” by the huge party and the many people that showed up.

The Howard Stern Show on SiriusXM is scheduled to end in 2015 when Stern’s contract is up; when asked if he is ready to retire, however, the radio mogul says, “I’m having the best time broadcasting with SiriusXM. That’s true. No hype. We have a great studio. No FCC. So if it continues to be this good, why not keep going for as long as I can?”
