The comedian upset the Sherlock Holmes star when he was hosting the 2005 Oscars.
And when he ran into him later, they almost got in a fight.
But former Hole rocker Love scared off the British-born star.
He said: 'I was sitting with Courtney Love, and she might've saved me from a fight. I'm not going to say ass-whipping because I don't think there'd be an ass-whipping.
'But you never know - he's hanging out with [director] Guy Ritchie. Those guys go at it. Those mother****ers are in shape. So Jude Law might whip my ass, I don't know.'
But Rock, 46, told a US magazine: 'Courtney kind of barked, or was growling, and that was it.'
Rock made a crack at the Academy Awards about Law being in 'every movie' that year and he still doesn't understand what the fuss is about.
He said: 'I didn't say Jude Law can't act. I didn't say Jude Law was in bad movies. I just said he's in every movie.'
