Stern was one of the first to spill details about the star-studded wedding. "I love him," Stern said of Theroux, 44, during his SiriusXM show. "I love him and I told Jennifer she deserves 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!"
