Bryce Hall is clapping back at Billie Eilish after she was heard wondering why a bunch of TikTok stars were at the People's Choice Awards ... sarcastically apologizing for her disgust.
The internet superstar responded to Billie on, where else, TikTok ... jokingly saying he was sorry for not acknowledging her greatness or bowing down to her at the award show they both attended.
As we reported ... Billie was filmed chatting with fellow singer Kylie Minogue at Sunday's People's Choice Awards when cameras caught her pointing out that there was a bunch of TikTokers in the house.
Billie was clearly not a fan of the TikTok contingent ... which included Bryce, Tana Mongeau, Chris Olsen, Gigi Gorgeous, Alix Earle and James Charles ... among others.
Bryce says he and the rest of his TikTok pals were invited ... so Billie should direct her anger at the folks running the PCAs instead of the TikTok generation.
The response is dripping with sarcasm ... he also wipes away a fake tear and bows to Billie.
What's more, Bryce says he was a huge Billie supporter ... but now the incident has him rethinking his fandom, and he says he's not going to be posting TikToks with her music anymore.
Billie might be OK with that, though ... but it's pretty fascinating to see mainstream celebs and TikTok personalities clashing.
