Lily Allen vs. Courtney Love! (VIDEO)

A battle of pop & rock divas is in full swing, as Courtney Love and Lilly Allen are going head-to-head in a bitter feud.

The rift apparently stems from Courtney Love being mad at Lily Allen for preventing other people from wearing Chanel designs at the BRIT Awards. (Really? That's what Courtney Love is up in arms about? Sounds more like something Lauren Conrad or Heidi Montag would feud over, but maybe Courtney is more like them than we want to admit.)

Courtney Blasted Lily Allen for this last week, and Allen, who has an exclusive deal with Chanel to represent them, was reportedly stung by the twitter blasts.

Then at the NME awards they reportedly butted heads in person, and Lily Allen walked away crying.

Then the next day Courtney hit twitter again with more barbs for Lily: "Pretty darn rich coming from someone who starts nonsensical fights with people out of insecure jealousy on a weekly basis. At least when I've started fights with people its because they [bleep] w (with) my kid or [bleep] w my $ (money). No further comment, hatred is not my drink, I don't like jealousy, vindictiveness, stalkers, selfishness and dishonesty, that's just me!"

Courtney Love continued her feud with Lily Allen at an awards show in London on Wednesday, when the British pop star reportedly left the ceremony in tears after a vicious bust-up with the rocker. The Hole front woman recently blasted Allen in a series of posts on her Twitter.com page, accusing the singer of blocking all other stars from wearing Chanel designs to the BRIT Awards because of her exclusive deal with the brand. And the ill feeling continued when the pair met at the NME Awards in London on Wednesday night, with Allen fleeing in tears after a ferocious war of words with Love, according to NME.com.
