Stephen Colbert and Seth Meyers take their best guess as to what Frances McDormand's outfit was supposed to be.
It was especially personal for Jimmy Fallon and Stephen Colbert, who were in attendance at the event themed "Heavenly Bodies: Fashion and the Catholic Imagination." In fact, Colbert was named one of the best-dressed by Esquire. Even better, the two decided to fully embrace the spirit of the event -- which is at least in part about photo ops -- by partnering for a smoldering shot of their own.
Jimmy Kimmel and Seth Meyers got in on the action of critiquing the fashion as well. Quite honestly, with some of these looks, it's like the celebrities were intentionally choosing their outfits to be the setup for a late-night punchline.
"Jimmy Kimmel Live"
"It's like a costume party at the Metropolitan Museum of Art," Kimmel said, explaining it to his audience so he could start showing off some of the looks with some context.
With the theme surrounding the "Catholic Imagination," there was plenty of Christian imagery to peruse. "Kim Kardashian had a cross on her stomach and on her haunch there," Kimmel said, flashing up a photo. "J.Lo had a crucifix on her center there like a superhero, Cardi B had an altar on her head."
"Forgive them Lord, they know not what they wear," he joked before describing Sarah Jessica Parker's fashion choice as "a lamp post at Mar-a-Lago" and Jared Leto, who "looks like Jesus just got back from Coachella."
"Late Night with Seth Meyers"
This NBC host didn't spend nearly as much time on the Met Gala as his late-night peers, but that didn't mean he could ignore it entirely. This is because Catholocism wasn't the only inspiration.
Or maybe it was. Honestly, we're not entirely sure what the inspiration was for Frances McDormand's unique ensemble.
"In keeping with the theme of Catholocism and fashion, Rihanna attended the event dressed as the Pope, while Frances McDormand dressed as -- Egypt being attacked by locusts?" Meyers joked.
"Late Show with Stephen Colbert"
The CBS star went with another theory for Frances McDormand's greenery, saying she "came dressed as a ficus." He also poked fun at Rihanna ("the disco bishop") and Katy Perry, who "found a way to beat the traffic and get there faster than anyone else," seeing as her outfit came with wings.
"It was like 'Eyes Wide Shut,'" he said of the attendant monks and other Catholic imagery. "It felt like either the whole evening was going to end in a giant-ass pile or they were going to kill us."
He then gave a shoutout to his lovely wife, who joined him at the event. "The guy wearing grandpa's couch cushion there, that's me," he pointed out, before sharing the picture taken of him and Jimmy Fallon together. "Just two altar boys getting ready to meet the Bishop," he joked.
"The Tonight Show Starring Jimmy Fallon"
The NBC star admitted he has no idea why he's been invited to this event for the past 10 years. "I really have no business going there, I'm a comedian," he said.
But while he was there, he took over GQ's Instagram, and was asked if he had any red carpet advice. "I said, 'Never follow a Kardashian.' 'Cause they're going to take all the attention. That's all people really want to see is a beautiful Kardashian in a nice dress and that's all people care about."
So what happened next? "I was waiting to go to the red carpet in a holding area and I was right behind Kim Kardashian," he laughed. "And then behind me was Cardi B. I was like, 'No one's even gonna know I'm there.'"
