The much-awaited professional reunion of friends and former EXO members Luhan and Kris Wu finally happened on Chinese survival show Produce Camp 2020.

In a special stage, Luhan and Kris performed their collaboration song 'Coffee.' This marks the first time the song is performed since its surprise release back in April.

Luhan starts singing alone on stage then Kris suddenly makes an appearance during his part in the track.

Watch Luhan and Kris perform 'Coffee' for the first time here:

After much speculation, Kris has made an appearance on Produce Camp 2020 as a special mentor. He joins Luhan and another friend and fellow former EXO member Tao who are both regular mentors on the show.

The three have looked back on their lives as trainees as well as their experiences as performers to provide constructive criticism for the performances of the show's contestants.

Produce Camp 2020 is the third season of the Produce 101 series in China and features female trainees hoping to debut as idols.

It is the Chinese version of MNET's popular talent competition franchise, Produce 101.
