'iCarly' Cast Condemns Racism After Laci Mosley Calls Out Hateful DMs

Miranda Cosgrove now has a Black BFF in the "iCarly" reboot -- which is unfortunately receiving hateful and racist backlash that she and the rest of the cast are stamping out.

Actress Laci Mosley is cast as Harper in the revived series -- which now follows Carly in her 20s -- who plays the main character's new best pal/roommate ... seemingly replacing Carly's old friend from the OG show, Sam Puckett. At least that's what trolls thought, anyway.

Apparently, folks were harassing Laci for her appearance in the show -- amid the absence of actress Jennette McCurdy, who played Sam -- and some were even calling her the n-word and other racist epithets ... so claims Laci, who called out the online hate.

She clarified she wasn't "replacing" anybody, and if people continued trolling her in her DMs, they'd be blocked. Her cries were echoed by Paramount -- the parent company of Nickelodeon -- and even Miranda herself.

The company issued a statement saying they were proud of the racially diverse cast for the new "iCarly" show -- and that any forms of racism being directed at their actors of color were not acceptable. MC reposted that same message to her IG Story.

One interesting twist here ... many Black fans of the show have also chimed in on Laci's casting, and some seem to think it's a case of PC overcorrecting and/or pandering on the part of Paramount.

One user wrote, "did they seriously just do the whole Black bestfriend trope with ICarly??? Man f*** all of that." There are lots of other tweets from other Black people that have similar sentiments.
