We could revel in it, in like a "TOLD YOU it was going to happen" sorta way, but it's just too f***ing obvious even for us.

As it happens, this latest spat was orchestrated by heat, because they're canny folk who know it'll get them a rake load of coverage because we need summat to gossip about.

They just so happened to be interviewing Hopkins (with the aid of a celebrity wheel) when they asked her (on a whim, natch) to vent her views regarding Lily Allen. Then the inevitable happened; she said Allen's journey into motherhood involved "gaining two stone and looking pretty hideous."

If that weren't enough goading, Hopkins then decided to add the usual red rag involving Keith Allen, saying Lily is "only famous for having a famous dad." Here's the video of her saying all that stuff, and more, courtesy of heatworld.com. Incidentally, Peaches Geldof, Kelly Brook, Kim Kardashian, Kelly Osbourne, Justin Bieber and people called 'Rebecca' also get "Katiefied." Enjoy the soundtrack.

Did Lily Allen take the higher ground and ignore the prole? Nay. Here's what she retorted on twitter:

"@KatieHopkins: I am not famous for having a famous dad, I doubt that most of my fan base have a clue who my father is.”

Then, she addressed the extremely hard stuff.

"Yes, after tragically loosing a child so late in to 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. I wasn't exercising because I didn't want to take any risks, and funnily enough, the survival of my children felt more important than being thin.”

And, funnily enough, Katie didn't have a response to that.

Lily added: "To you. There's always plastic surgery ya know. Maybe they could sew your mouth up while they fix the rest of you."

Then, she saw sense...
