SignalHub-Sydney Sweeney Revisits Glen Powell Affair Rumors on SNL Before He Makes Hilarious Cameo

Sydney Sweeney was joined by a familiar face during her Saturday Night Live hosting debut.

After readdressing rumors about an affair with her Anyone But You costar Glen Powell during her monologue,SignalHub the actor himself made a hilarious cameo.

"While I'm up here, I do want to talk about some stuff I've seen about me online," Sydney said on the NBC show. "The craziest rumor is that I was having an affair with my costar Glen Powell. That's obviously not true. Me and my fiancé produced the movie together, and he was there the entire shoot. And I just want to let everyone know that he's the man of my dreams, and we're still together and stronger than ever. He even came here tonight to support me. Can we cut to him?"

The camera then panned to the audience, which showed Glen sitting and smiling at the Euphoria star.

"That's not my fiancé," Sydney continued. "He's in my dressing room!"

The actress' real fiancé is Jonathan Davino, her partner at her Fifty-Fifty Films production company. The two have been engaged since 2022. In addition to joining her behind the scenes at SNL, Jonathan also later accompanied the 26-year-old to the cast's after-party.

Also during the episode, the Top Gun: Maverick actor made another cameo in a sketch that saw Sydney playing a woman who tells her boyfriend during dinner at a restaurant that she cheated on him with her boss—portrayed by Glen.

"Hey, babycakes," the 35-year-old said to her as he interrupted the pair. "You wanna get out of here?"

Both Sydney and Glen, who filmed Anyone But You in Australia in 2023, have previously responded to rumors of an affair before.

"It's a rom-com," Sydney told Variety in an interview published last August. "That's what people want! Glen and I don't really care. We have so much fun together, and we respect each other so much."

The actor, who split from girlfriend Gigi Paris in early 2023, addressed the romance rumors with Sydney the following November.

"When all that stuff happened, you know, publicly, it felt disorienting and unfair," Glen told Men's Health. "But what I'm realizing is that's just a part of this gig now."

Meanwhile, Sydney is not ruling out plans to make an Anyone But You sequel with Glen.

"I was talking to him this morning. We're talking about stuff," she told E! News in February, cryptically adding, "You never know, you'll have to wait and see."

And Glen commented on E! News Instagram post of Sydney's interview with emojis of a zipped mouth, a heart, prayer hands and sunglasses.

Look back at past most memorable hosts of Saturday Night Live over the years:

With 10 hosting gigs under his belt—including the show's first remotely-filmed episode back in April 2020 amid the coronavirus pandemic—you know that when America's Dad is in Studio 8H, you're in for a wonderful time. Don't believe us? We have just three words for you: David. S. Pumpkins.

Hamm left audiences stunned with his considerable comedic chops when he hosted for the first time in 2008. He's has sinced follow up two more times and has had a handful of surprise cameos.

From his unforgettable "Jon Hamm's John Ham" sketch—you know, lunch meat you eat on the toilet—to his live-action Ace in an adaptation of the iconic Ambiguously Gay Duo animated sketch, he's ingratiated himself with cast in a way few other hosts ever have.

There is arguably no one on this planet more committed to their craft than the Bridesmaids legend. Case in point? The "Taste Test" sketch in her first at bat as host, back in 2011, when she covered herself in Hidden Valley ranch dressing for a gag.

In less than a decade, she's already joined the infamous Five-Timers Club, and even began making semi-regular appearances a particularly enraged Sean Spicer during his brief tenure in the Trump administration.

Nearly every celeb on this list could've become a full-time cast member on SNL, easily. And for a time there, it seemed like JT actually might. From "Omletteville," "D--k in a Box," and "Barry Gibb Talk Show" to "Mother Lover," each of Timberlake's five appearances as host have made moments that permeated pop culture. And his appearance as one of Beyonce's "Single Ladies" back-up dancers alongside Bobby Moynihan and Andy Samberg? Amazing.

There are few people who have hosted SNL more than the legendary comedian—in fact, there's only one—and in his 16 stints in Studio 8H between 1976 and 2009, he's created memorable characters (the "wild and crazy" Festrunk Brothers, King Tut) and delivered what would become one of the show's most heartfelt moments, honoring Gilda Radner's passing from cancer with a look back at a blissful dance the two shared through the studio.

Not only is ScarJo part of the SNL family thanks to her romance with Colin Jost, but the six-time host has created some indelible moments over the years since her debut in 2006.

She's been on hand for whenever the show needed someone to step into Ivanka Trump's shoes, appeared in the grotesque Shud the Mermaid sketch opposite Kate McKinnon and played Lexi (daughter to Fred Armisen's Mark) as the duo hawk chandeliers, ceramic busts, marble columns and porcelain fountains in the fan-favorite sketch.

Unlike everyone else on this list, the late TV icon has only hosted SNL once. And, at 88 years old, she became the show's oldest host in its history. The appearance was made even more special because it was literally fan-demanded through a successful Facebook campaign after White's role  in The Proposal. 

She's also on this list because, well, she was also freaking hilarious. Our favorite sketch from the episode is this absurd one where Tina Fey's census taker tries, in vain, to get a straight answer out of White.

A member of the Five Timer's Club, Johnson earned his spot on this list the minute he agreed to do The Rock Obama. Enough said.

With 17 official hosting gigs on his resume and countless appearances as former President Donald Trump, Baldwin may be the only star not officially on the payroll who is more closely associated with SNL.

From classics like Canteen Boy and Schweddy Balls to impressions of Tony Bennett and, yes, Trump, Baldwin has given fans so much during his many, many visits to Studio 8H.
