Naomi Campbell needs a kick up the backside, according to lesbian comedian Rosie O’Donnell.

O’Donnell challenged the supermodel to a duel after discovering she allegedly assaulted her assistant with a mobile phone in New York last month.

She said: “To make matters worse she had that jewel-encrusted cell phone, that’s got to score with the diamonds.

“She looks like you could snap her in two but she’s a tough-ass, kick-ass woman.

And O’Donnell appears to see herself as the ideal candidate to sort the model out, “I would actually like to fight her. I think for all the people that she’s beaten up, I think she needs a big 200 pound (91kg) lesbian to kick her ass.”
