She speaks!

After ruminating on the matter for two days, Kendall Jenner is finally responding to Frances Bean Cobain's Twitter diss. Kurt Cobain and Courtney Love's daughter sent a string of tweets bashing the reality darling on Tuesday -- even calling her a "f--king idiot" -- for tweeting "just wish things could be easier sometimes mann."

"An individuals feelings are relative to their environment," Kendall fired back yesterday. "You don't know me, you don't even know what I was referring to."

The 17-year-old also said she understands that she leads an affluent lifestyle, but she has the right to vent about her problems -- big or small. "I am aware that i am very privileged and blessed, and im thankful for that everyday, i know there are greater problems in the world," she wrote.

In response to the 20-year-old's slam that Kendall wasn't cognisant of the "kids on earth abandoned&homeless" or "CANCER, famine, poverty, draught, disease, natural disasters, Death," the Kardashian half-sister said, "I pray for those people every night and give back as much as i can. so who are u to judge me?"

Probably still upset about the Twitter beating she received, Kendall looked glum while walking to the gym yesterday morning. She hopefully got a restful night's sleep after getting that weight off her shoulders. You know outspoken Khloe and Kourtney were proud.
