Lily Allen Blasts British TV Personality for Calling Her Fat, Shows Off Slim Body on Instagram

Check out the singer's rocking' body!

Lily Allen is firing back at British TV personality Katie Hopkins!

Hopkins, who's known across the pond for her shock jock antics, recent slammed the 28-year-old singer during an interview with Heat.

"I'm not one for Lily Allen really," Hopkins said. "I quite liked her when she was singing and kind of interesting and then she went off to tell us all about being a mother. She was removing herself from the spotlight because she wanted to be a mother and that largely I think involved gaining two stone (about 28 pounds) and looking pretty hideous."

Hopkins added, "So then she decided that was boring and now she wasn't going to be a mother any more, she was going to be a singer again. Like [socialite] Peaches (Geldof), she is just famous for having a famous dad."

Allen, who's been vocal about her weight issues following her November 2010 miscarriage and the birth of her second daughter last year, replied to the nasty remarks via Twitter (they've 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 wrote. "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."

"The two pregnancies that followed were terrifying because of what had happened before and I was pretty much on bed rest for 20 months," Allen continued, adding, "I wasn't exercising because I didn't want to take any risks, and funnily enough, survival of my children felt more important than being thin."

"Can somebody tell me what Katie Hopkins does except go on telly slagging off girls half her age?" the singer concluded. "Ps 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."

And to top it all off, Allen shared an Instagram pic of her in a skin-tight dress looking thinner than ever! "Just going to the shop, want anything Katie?" Allen captioned the hot shot.
