You can count Jimmy Fallon among those completely blown away by Justin Timberlake
and Jessica Biel
's lavish Italian wedding
"It was just insane. Everything was just beautiful. It was really, really a beautiful night, the perfect temperature," the talk-show host revealed Thursday on Bravo's Watch What Happens Live
After joking that he had signed a confidentiality agreement and couldn't say much, Fallon, 38, had plenty to say about how lovely the bride looked
on her big day.
"She's looked gorgeous. She's beautiful. She looked like a princess," Fallon said of Biel, 30.
Fallon said it wasn't just a beautiful night, it was a fun night as well. "Questlove deejayed. He's the best deejay in the world," he said.
"And I'm just a sucker for weddings," Fallon added. "I'm a fun person to invite to a wedding. I dance. I get up. I drink. But then I weep!"
