Jennifer Aniston and Justin Theroux did an amazing job at keeping their wedding last week a secret and they made sure all their famous friends did the same. While it must have been hard for some of the stars to keep quiet, they kept their promise, but now that the wedding has happened and, Howard Stern couldn't wait to share all the details.

On Monday morning during his SiriusXM radio show, the 61-year-old host revealed that he was one of the few that knew this would be happening in advance, and that's only because he was asked to give a speech, according to Us Weekly. He was even "nervous" at first because of how secretive the two are about everything. Now, he's holding nothing back and let us in on all the details from the event, including the guest list and the fact that Jimmy Kimmel officiated the ceremony!

"Jimmy was the preacher. He did a beautiful job. I didn't think he'd get through it," Stern revealed. "Ellen was mad that I made fun of Jimmy for crying."

He went on to explain that even though he was "miserable" at the thought of having to give a speech, he had the entire crowd laughing and even had a few amazing things to say about Theroux.

"I like him, I really admire him. I even said in my speech to them that if one of my daughters brought home a guy like Justin, I'd be very pleased," he said. "I love him. I told Jennifer that she deserved a guy like this, because after all, she's been very sweet and generous with us. But Justin and his body. His abs, his ass. Look at him. I'm giddy over him!"

As for his famous humor, Stern spent the first 10 minutes of his speech complaining about the tiny chairs and the fact that all the guests cell phones were taken away as soon as they arrived.

"Why can't I have my cell phone? I don't want to take a picture of you two! I really don't," he joked. "I want my cell phone so after I make this speech I can call my car and get the f--k outta here! People were laughing at my misery."

The star-studded guest list included Orlando Bloom, Ellen DeGeneres, Portia de Rossi, Lisa Kudrow, Whitney Cummings, Chelsea Handler and Courtney Cox, who was the last to leave the party.
