Corey Feldman’s old “Stand by Me” castmate, Jerry O’Connell, came to the support of his fellow former child star after Feldman’s eccentric musical performance on “Today” Friday generated mockery as the clip went viral.

“Proud of you @Corey_Feldman,” tweeted 42-year-old prolific actor and voice-over performer O’Connell. As well, “Frozen” and “The Book of Mormon” star Josh Gad, 35, posted a cryptic tweet reading, “Saw #CoreyFeldman trending and prayed it was an announcement for #Goonies2. Sadly it was not.”

Feldman, 45 — whose youthful films include “The Goonies” (1985), “Stand by Me” (1986) and “The Lost Boys” (1987) and who has appeared in dozens of mostly low-budget movies since — himself responded to the backlash over his morning-show performance of “Go 4 It,” from his fifth album, “Angelic 2 the Core.”

“We just wanted to tell everybody that, like, it’s been really painful,” an emotional Feldman said on a Facebook Live post that was later deleted, reported People magazine Sunday. “We put ourselves out there and we did the best that we could,” he said, according to the magazine’s transcript. “And, like, I’ve never had such mean things said about me. Like constantly.”

“All we can say is that we tried really hard,” Feldman said tearfully. “Because we love our fans and we just wanted to give them the best show that we could. But we don’t deserve . . . these things that are said about us are awful.”

He went on to say, “It was a song, OK? It wasn’t that weird, adding, “I’m sorry if it’s not good enough for you, but you don’t have to beat us up. I just want to say that, like, why is it okay to, like, publicly shame us? . . . I don’t understand . . . It’s, like, not PC to, like, say somebody is fat or somebody is white or somebody is black or somebody is yellow or green or if they have a short leg or if they have a missing finger. Like, we can’t talk about these things. But it’s okay to bash Corey Feldman and the Angels.”

Feldman added, “Public shaming should not be accepted, no matter who you are. It doesn’t matter if they’re a celebrity or not. We deserve love and we deserve, like, normal life . . . It’s not okay, it’s not acceptable to call us freaks, weirdos, losers, whatever.”
