Yesterday, Katy Perry came under fire for the ~controversial~ topics she raised while hosting the VMAs from celebrity bbs to, erm, pee.
But it was a swipe at Justin Bieber that got peeps REALLY riled up.
Katy came on stage carrying a fake baby and joked about how *certain* celebs have babies to boost their social media presence.
"My management told me I should have a fake baby to increase the publicity and have more followers," she joked.
Then she went in for even more shade, saying that her fake baby "knows all the words to 'Despacito', unlike some other babies I know."
Obvs referring to Justin who famously doesn't know the lyrics to the catchy song he features on and fakes the words while performing it live.
Meanwhile, the internet is high-key LOSING IT over Katy's drive-by shade of the Biebs.
