KELLY OSBOURNE - KELLY OSBOURNE: CHRISTINA HAS ALWAYS BEEN 'HORRIBLE'

KELLY OSBOURNE has lifted the lid on her feud with CHRISTINA AGUILERA - insisting the BEAUTIFUL singer has been "horrible her whole life".

SHUT UP! star Kelly, 19, famously fell out with Aguilera after calling her a 'c**t' during an interview, and outspoken Kelly is happy to let the public know she has no intention of making friends with her DIRRTY nemesis.

She fumes, "Everyone I know and have met hates Christina. She's very nasty. I've known her since I was ten and it's fair to say that she's been horrible her whole life.

"If Christina offered me a white flag I'd kick her in the face. I couldn't even be in the same room as her because I know she would probably come up to me and punch me, and then hide behind some ten-foot tall security guard like a p***y.

"She hates me because I point out the true things and the truth hurts. She's so childish and superficial, and the reason she's like that is because she was never in contact with kids of her own age when she was growing up, so she never matured."
