On Wednesday, Thorne took to her Twitter to call out Mongeau after the YouTuber was reportedly spotted at dinner with their ex, rapper Mod Sun, per Page Six. The three were previously in a polyamorous relationship.
In response, Mongeau doubled down on her confusion, asking Thorne what she was doing.
"I have no idea why you're mad, I've been texting you every minute since you tweeted, and for you to be tweeting me something as hurtful as saying I dated you for Twitter is literally fucking nuts & if you honestly think that damn I lost you," Mongeau wrote, while also liking tweets about how Thorne had gone "too far," per BuzzFeed.
dude what are you doing bella? like i have no idea why you’re mad, i’ve been texting you every minute since you tweeted, and for you to be tweeting me something as hurtful as saying I dated you for Twitter is literally fucking nuts & if you honestly think that damn i lost you
That said, this isn't the first time Thorne's posted about her exes. Last month, the actor reacted to news of Mongeau's engagement to fellow YouTuber Jake Paul by posting a teary-eyed selfie of herself alongside the caption, "When ur ex gets engaged."
Not only that, but earlier this year, Thorne got into an online argument with Mod Sun after he said that he was going to sell her stuff on eBay.
In response to his "joke," Thorne called him a "pussy" and accused him of "[calling] the cops on me when I wanted my computer" — an allegation Mod Sun responded to by calling her "not the most trustworthy person," and insisting that he had already asked her to "swap" stuff several times.
