‘NSYNC’s Coachella reunion was Justin Timberlake-approved.

Although Timberlake, 38, didn’t join his bandmates for their surprise performance with Ariana Grande during her Sunday night Coachella set, the Man of the Woods singer made sure to cheer his pals on from a distance.

Sharing a photograph of Lance Bass, JC Chasez, Joey Fatone and Chris Kirkpatrick cozying up to the 25-year-old pop star backstage, Timberlake sent his congratulations.

“You guys killed it last night,” he wrote on Monday, adding a raised hands emoji.

Grande reflected on the collaboration Monday, captioning her Instagram post with a heartfelt message. “I’ll be recovering from this moment for the next twenty years tbh. the nicest human beings possible. It can go either way when you meet your childhood heroes and no one has ever been kinder or cooler or sillier or more lovely to be around. ever!” she wrote.

“Also how the f— do y’all still sound and dance exactly like you did when my mom and I followed you around on tour when i was 5? thank you thank you thank you for your time and energy and i love you so much forever,” she added.

Days after Grande began dropping hints that the boy band would make an appearance during her set, the group walked out to perform with Grande on her hit song “Break Up With Your Girlfriend, I’m Bored,” which samples “It Makes Me Ill,” an old ‘NSYNC song from their 2000 album,

.

“I’ve been waiting all my motherf—ing life to say this: ‘NSYNC,” Grande said before she and the group performed the 1997 classic, “Tearin’ Up My Heart.”

“Coachella, this has been a dream of ours, thank you Ariana!” the band added.
