Lady Gaga delivered a performance that was fitting for Saturday Night Live‘s “Homecoming Concert,” a special musical event in celebration of the show’s 50th anniversary.

While some audience members at Radio City Music Hall in New York might have expected the star to sing one of her recently released singles, she kicked things off with none other than Andy Samberg himself in a wig and cowboy hat. The former cast member attempted to sub-in for Bradley Cooper for a cover of “Shallow,” the hit track from Gaga and Cooper’s 2018 film A Star Is Born. However, things were cut short when Gaga informed Samberg, “I gotta stop you, because it’s bad,” and recommended they do something “more in your vocal range.”

“There is one song, but Justin [Timberlake’s] not here to do his parts,” Samberg offered. Undeterred, Gaga replied, “Andy, don’t be a bitch. I’ll do it with you,” before the duo effortlessly pivoted to the Lonely Island classic, “Dick in a Box.” (The song made its debut during SNL‘s 2006 Christmas episode with Timberlake.)

Soon, Gaga and Samberg shared the stage with Bad Bunny, T-Pain, Chris Parnell, Eddie Vedder, and former Lonely Island member Jorma Taccone for a whacky mashup of “Motherlove,” “Lazy Sunday,” “I’m On a Boat,” “Jack Sparrow,” and “Jizz in My Pants.”

The musical event kicks off a weekend that will conclude with SNL‘s 50th anniversary special airing on NBC on Sunday. The episode is set to feature a star-studded lineup of returning cast members and special guests, including Tom Hanks, Bad Bunny, Kim Kardashian, Martin Short, Robert De Niro, Sabrina Carpenter, Adam Driver, and more.
