Rock star celebrity kid Frances Bean Cobain has launched into a huge Twitter tirade against fellow teen celeb Kendall Jenner — and she’s not holding anything back! The 20-year-old daughter of Courtney Love and the late Kurt Cobain posted an expletive-ridden string of tweets directed at Kendall on May 21.

It all started when the Kardashian sib, 17, tweeted, “just wish things could be easier sometimes mann”

Sounds harmless enough to us, but Frances had a different idea. “@KendallJenner oh shh. There are kids on earth abandoned&homeless who forcibly drink contaminated water because clean water isn't accessible,” she quickly posted.

That wasn’t all. “@KendallJenner oh ya, not to mention, CANCER, famine, poverty, draught, [sic] disease, natural disasters, Death. F--k, Humans are so self involved.”

A sympathetic fan chimed in, “at last someone has some brains. Thanks Frances. We are the scum that sucks the earth dry.”

Frances responded, “i'd rather be a scumbag than a f--king idiot. Praise high IQ's, good taste & awareness about the state of the world.”

For those of you keeping track at home, she’s already called Kendall “self involved” and implied that she’s a “f--king idiot.” But just in cased that wasn’t enough, Frances added, “I'd like to thank my parents for providing me with a high IQ & I'd like to thank my grams for encouraging me not to be a self absorbed idiot”

Her mother, Courtney Love, even chimed in — though it’s unclear if she was fully aware of her daughter’s little anti-Kardashian tirade or not. “id [sic] like to thank your grams for being a good grams i will always love her.”

Kendall has not responded directly to Frances on Twitter, but that doesn’t mean she’s ignorant of what went down. The next evening, Kendall tweeted a simple, “not playin dees gamess.” Your move, Frances.
