"Your 'fav' that use to be in that lil pop group is racist but WBK", she initially tweeted.
When fans were asking who she meant, she said: "The one that' dating the fine gay guy."
Her rant concluded by her saying that she slept with the singer's boyfriend to get back at her 'racism'. While she didn't clarify if it was the "fine gay guy" or another boyfriend, she went on to claim that he had a dick the size of her "baby teeth".
You can't make this kind of stuff up.
People initially believed the tweets were about Camila because she is a former girl-band member, who has in the past been accused of racism and apologised for it. It ties in with her and Shawn as he has constantly been questioned about his sexuality.
Naturally, Twitter went OFF:
You can see Camila's 'racist' tweets from 2013 where she apologised below.
She allegedly used the 'n' word along with racist language like, "hood rat".
"I get how anybody that doesn’t know me would think those things about me, I was immature and young and joking (not an excuse) but I apologise."
Camila nor Shawn have replied to any of the tweets.
They probably haven't even seen them yet, they are very busy making out.
