Corey Feldman sings and feels the sting of social media.

FOX's Michele Pollino reports from Los Angeles:

Corey Feldman was attacked on social media following his "Today" show performance of his new single, "Go 4 It," on the NBC morning show.

(Feldman) "Oh we're not gonna stop until we reach the top."

Many on Twitter were down right nasty to Feldman, prompting the actor to go on Facebook live to say "We can't get out of bed right now," in a now-deleted post, according to People.

"We're petrified to even go out. We put ourselves out there and we did the best that we could," but Pink came to the actors rescue writing, "Well, I love ya, I know how much it takes to get up there and do your thing, keep your head up and know that you're loved!"
