Kim Kardashian Films Nicole Richie &Amp; Kris Jenner Singing Salt N Pepa

Nicole Richie and Kris Jenner were clearly had way too much time on their hands this week. They spent Wednesday rehearsing the 'Shoop' rap by Salt N Pepa in a dressing room while Kim Kardashian filmed the whole thing.

First off the pair can be seen practising their lines as Nic sits on momager Kris' knee. It's all very bizarre...

Then, after enough rehearsal, the lyrical duo put on a full performance... Complete with sideways baseball caps and the like.

Well, it's nice to see that Nicole and Kim - who have been friends since childhood - are spending their weekdays productively.
