Lady Gaga, Justin Bieber and BTS are among the stars set to make cameos in the upcoming Friends reunion special.

After months of anticipation, Friends: The Reunion will debut on US streaming service HBO Max on Thursday, May 27th.

As reported by Variety, the special will focus on Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer as they return to the show’s original soundstage at the Warner Brothers Studio lot for a non-scripted reunion.

However, the special will also feature a number of guest stars, including some of the biggest names in music.

That’s right, Bieber, Gaga and BTS will appear at the reunion, along with tons of other big-name celebs.

David Beckham. James Corden, Cindy Crawford, Cara Delevingne, Kit Harrington, Mindy Kaling and Malala Yousafzai are all also joining in on the action.

As if that wasn’t enough, it will also feature appearances from some of the show’s guest stars including Tom Selleck (Richard), Maggie Wheeler (Janice), Reece Witherspoon (Jill Green), Elliott Gould (Jack Geller), Christina Pickles (Judy Geller), Larry Hankin (Mr Heckles), Thomas Lennon (Joey’s hand twin) and James Michael Tyler (Gunther).

The announcement of the premiere date will no doubt come as a relief to many fans, given that it was originally supposed to air last year.

Originally set to film in February 2020, it was postponed until April this year due to production delays caused by the COVID-19 pandemic.

Although it’s not yet clear what role the superstar guests will play, we’re betting they’re huge Friends fans just like the rest of us mere mortals.
