Drop that mic, Lily Allen -- you just won this debate. After British TV personality Katie Hopkins said some horrifically negative things about the singer's weight, Allen took to social media to shut her up once and for all.

"I'm not one for Lily Allen, really," the host said in a recent interview. "I quite liked her when she was singing … [Then] she was removing herself from the spotlight because she wanted to be a mother — and that largely, I think, involved gaining two stone [the equivalent of 28 pounds] and looking pretty hideous … Like [socialite Peaches Geldof], she is just famous for having a famous dad." (Allen's father is actor/musician Keith Allen. Also, the singer has been pretty open about suffering from bulimia and facing two devastating miscarriages.)

After hearing such comments, Allen -- never the one to shy away from a debate -- took to Twitter in a series of tweets that have since been deleted.

"Katie Hopkins: I am not famous for having a famous dad. I doubt that most of my fan base have a clue who my father is," she began.

"Yes, after tragically losing a child so late into my pregnancy I may have gained a few pounds. I am one of many that find comfort in food." Not to mention that she was on bed rest and did not exercise during her subsequent pregnancies to be on the safe side.

"Funnily enough, survival of my children felt more important than being thin," she shot back. "Can somebody tell me what Katie Hopkins does except go on telly slagging off girls half her age? P.S. Katie looks are obviously important to you. There's always plastic surgery, ya know. Maybe they could sew your mouth up while they fix the rest of you."

By this point, Hopkins needed some ice for that killer burn, but Allen had one last point to make -- this time on Instagram.

"Going to the shop," she captioned the below photo of herself looking svelte and sexy. "Want anything Katie?"
