Boyband legend JC Chasez looked unrecognisable on Tuesday as he surprised theatregoers in New York by performing NSYNC’s biggest hit on stage.

The singer, 48, took to the stage to warm up the crowd at the & Juliet Sing Along gig at the Stephen Sondheim theatre.

JC, whose real name is Joshua Scott Chasez, looked worlds away from when he first shot to fame as part of NSYNC back in 1999.

He rocked a white t-shirt, grey bomber jacket and black trousers and completed his look with orange aviator sunglasses.

JC delighted fans as he showed off his incredible vocal talent as he performed NSYNC’s 2000 Bye Bye Bye.

The crowd went wild and were heard singing back the famous chorus as the star was joined on stage by the & Juliet cast.

The & Juliet Broadway’s official Instagram page shared a clip of JC performing and wrote: ‘Holding space for the lyrics of Bye, Bye, Bye.’

‘Yes, @jcchasezofficial you killed it as always!!! Thank you for this! We miss you so much; Nailed the caption and JC nailed the vocals. So glad I could witness this live!

‘One of the best voices of our time; THE voice of *NSYNC!; Those vocals; And this was when I was sobbing and hyperventilating’.

JC found fame in 1995 in NYSNC alongside Justin Timberlake, Chris Kirkpatrick, Joey Fatone, and Lance Bass. The band split in 2002.

Ten years later they briefly reunited at the 2013 MTV VMAs and last year they reunited for single Better Place for movie Trolls Band Together.

Earlier this year, four of the five members of the nineties boyband JC, Chris, Joey, and Lance – reunited at the world premiere of Deadpool & Wolverine in Manhattan without their most famous bandmate Timberlake.

The eight-time Grammy-nominated boyband put on a strong united front outside the David H. Koch Theater in Lincoln Center amid rumors of a potential stadium summer tour next year in honour of their 25th anniversary.

‘I’ll tell you what. We’re all in New York right now because we’re putting… no, I’m kidding!’ Chris joked to New York Living hours earlier.

‘We’re all talking again as you’ve seen some of the stuff we’ve done together lately. We have [two] new songs, which is a lot different than the last 20 or so years that we haven’t been together. So there’s a lot. There’s a lot we’re talking about. Nothing in stone yet…When we know, you’ll know.’

The 52-year-old NSYNC founder added: ‘I am [down], yeah. I’m doing the Pop 2000 [Tour] now, which is basically me by myself without those guys, so I miss them. We’re all buds. We’re all good friends.’

NSYNC have sold over 70M records, and they still get 8.9M monthly listeners on Spotify.
