Perry, 54, played Chandler Bing on the popular NBC series from 1994 to 2004.

The moment took place at Puth’s concert in Australia following reports that Perry died Saturday at his Los Angeles home from an apparent drowning.

Puth, 31, is scheduled to perform two back-to-back shows at the Margaret Court Arena in Melbourne on Sunday and Monday, according to the venue’s website.

Puth allowed fans to belt the theme song’s verse before joining in during the chorus. Afterward, he transitioned to his 2015 hit song, “See You Again.” Puth recorded the song with rapper Wiz Khalifa for the “Furious 7” soundtrack as a tribute to the late actor Paul Walker who starred in the movie franchise and died in a 2013 car crash.

In the comment section, fans praised Puth for honoring Perry.

“My heart is so full and broken all at once,” one user wrote.
