Cummings also confirmed that the famous couple's first dance as newlyweds was during a performance of Sia's "Chandelier."
"It was pretty good," the 33-year-old admitted.
Another highlight of the wedding was Howard Stern's "hilarious" speech. "All he did was talk about how he didn't know Justin well enough to be there," Cummings recalled.
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!"
