After Kourtney quickly disabled his account, Mason found a way to return, and go live with famous TikToker Addison Rae.
Addison asked Mason who his favourite beauty gurus are, to which Mason responded: "I don't really watch makeup YouTubers, but I think James [Charles] — he's really nice. Because Jeffree Star is, like, spoiled AF."
While Addison was quick to change the subject, the fans who heard were quick to spread the news to Jeffree.
According to Buzzfeed News, Jeffree later released an official response for Mason in a now-deleted tweet writing, "I had $500 in my bank account six years ago. Maybe he's confused with his own privilege versus mine being self-made, hopefully his father can educate him soon!"
Kourtney Kardashian said in an Instagram Live recently that: "he [Mason] started an Instagram yesterday and he didn't ask us. I did delete it because Scott and I felt like — he's 10," she went on. "I think there's an age limit with Instagram. I think it's 13."
Well, we can only imagine e how she's feeling now, watching her first-born involve himself in a feud with one of the messiest and most scathing personalities.
