SNL: Harry Styles To Pull Double Duty As Host And Musical Guest

Harry Styles is returning to "Saturday Night Live."

For the second time, Styles will pull double duty as host and musical guest of the March 14 episode of NBC's sketch comedy institution, the network has announced.

The Grammy Award winner's "Together, Together" tour launches this spring in support of his album, "Kiss All the Time. Disco, Occasionally.," due out March 6. He last served as host and musical guest of "SNL" in Season 45.

As previously reported, "Heated Rivalry" star Connor Storrie will host the February 28 episode, making his "SNL" debut. He'll be joined by Mumford & Sons, making their fourth appearance as musical guest.

Meanwhile, Ryan Gosling will host the March 7 episode, marking his fourth stint as host. Gorillaz will serve as musical guest for the first time.

Thus far this season, "SNL" has welcomed the likes of Bad Bunny, Sabrina Carpenter, and Glen Powell as hosts. Here, we're keeping a running list of each Season 51 "SNL" host and musical guest, so you can see who's already appeared on the show and who's coming up next. Read on to get the full rundown, and let us know in the comments what you think about the forthcoming "SNL" guests!

Season 51 kicked off with chart-topping superstar Bad Bunny hosting for the second time, as well as three previous appearances as musical guest. (Doja Cat made her "SNL" debut as musical guest.) 

Bad Bunny began his hosting stint with a monologue that poked fun at the controversy surrounding his upcoming Super Bowl halftime show performance, adding a message to his fans in Spanish. The episode also rode the buzz behind Netflix's smash hit "KPop Demon Hunters" with a sketch where Bad Bunny played a super fan of the movie; the singing voices behind the animated K-pop girl group made a cameo, too, singing their hit song "Golden."

Oct. 11 marked 50 years since "SNL" debuted on NBC, and the show marked the occasion by bringing back an old friend. Poehler, an "SNL" cast member from 2001 to 2008, returned to host for the third time, with musical guest Role Model making his "SNL" debut.

Poehler was joined by her old pal Tina Fey in the cold open, with the pair playing Trump staffers Pam Bondi and Kristi Noem in a parody of Bondi's combative Senate testimony. Poehler and Fey then reunited with fellow "SNL" alum Seth Meyers on Weekend Update, with the trio taking on current anchors Colin Jost and Michael Che in a heated joke-off.

Pop star Sabrina Carpenter made her "SNL" hosting debut in October, pulling double duty as musical guest as well. (She served once before as musical guest, as well as appearing in this year's "SNL50" anniversary special.) 

The episode brought back Marcello Hernandez's recurring character Domingo, as Carpenter played one of the giggling friends singing about the illicit affair between Domingo and Chloe Fineman's Kelsey. Carpenter also starred with "SNL" cast member Bowen Yang in a pre-taped music video about middle school dances and the raging hormones that lead to grinding on the dance floor.  

Miles Teller made his second appearance as "SNL" host this season, backed up by musical guest Brandi Carlile, who appeared for the fourth time.

Teller's episode began with a parody of the New York City mayoral race, with former hosts Ramy Youssef and Shane Gillis playing candidates Zohran Mamdani and Curtis Sliwa, while Teller played candidate Andrew Cuomo. Teller later played both Property Brothers (!) in a sketch as the HGTV hosts helped President Donald Trump with his extensive White House renovations.

Stand-up comic and Golden Globes host Nikki Glaser graced the Studio 8H stage for the first time as host in November, with fellow "SNL" rookie sombr as musical guest. 

Glaser's episode included a parody of the Disney classic "Beauty and the Beast," with Glaser's Belle being romanced by YouTube king Mr. Beast. It also featured the triumphant return of "SNL" alum Pete Davidson, who dropped by Weekend Update to defend his purchase of an old Staten Island Ferry boat... and to jab at "SNL" boss Lorne Michaels while he was at it. 

Glen Powell hosted "SNL" for the first time as he promoted his starring role in the big-screen remake of "The Running Man." He was joined by musical guest Olivia Dean, making her "SNL" debut.

In the episode, former "SNL" cast member Will Forte returned to reprise his role as hapless hero MacGruber in a series of pre-taped sketches. Plus, Powell played a guy who invited stand-up comic Sebastian Maniscalco to his bachelor party, with Marcello Hernández uncorking a killer impression of the comedian.  

Frequent "SNL" host Melissa McCarthy returned for a December episode, with first-time musical guest Dijon. The episode kicked off with Colin Jost playing Secretary of War Pete Hegseth at a press conference, berating reporters while James Austin Johnson's Donald Trump dozed off mid-speech.

Rising British star Josh O'Connor made his debut as "SNL" host in December, with musical guest Lily Allen. His episode saw him play a sensitive male stripper alongside featured player Ben Marshall, wearing fuzzy sweaters and wooing the ladies with their strong feminist views and empathetic eyes. 

Pop songstress Ariana Grande returned to host "SNL's" annual pre-Christmas episode, which included a farewell to cast member Bowen Yang, with Grande and musical guest Cher helping to send him off in style. Grande also delivered a comical rendition of the Mariah Carey holiday classic "All I Want for Christmas Is You" during her monologue, puzzling over what kind of gift she could buy for her cousin's boyfriend.

Finn Wolfhard was joined by his "Stranger Things" co-stars Gaten Matarazzo and Caleb McLaughlin during his debut monologue as "SNL" host. A$AP Rocky served as musical guest. The episode also featured a steamy crossover of "Harry Potter" and "Heated Rivalry," with Wolfhard playing a boy wizard who gets up close and personal with Ben Marshall's Ron Weasley. 

"One Battle After Another" co-star and freshly minted Oscar nominee Teyana Taylor hosted "SNL" in January, with musical guest Geese. One highlight saw Taylor don a bald wig and a fake mustache to play a grandfather who can't resist dancing at a wedding... even though his body won't comply. Plus, the episode opened with James Austin Johnson's Donald Trump accepting a slew of awards, with "SNL" alum Mike Myers returning to play billionaire Elon Musk.  

"SNL" wrapped up its January run by welcoming "Succession" and "Big Little Lies" alum Alexander Skarsgård to host for the first time. Cardi B joined him as musical guest, marking her second "SNL" appearance. The episode kicked off with "SNL" alum Pete Davidson returning to play Trump border czar Tom Homan trying to rein in ICE agents in Minneapolis.
