Kendra Wilkinson: I Can't Remember My Own Rap Lyrics

Kendra Wilkinson's rap career is off to a rocky start ... it seems whatever she recorded she did under the influence, because she just can't spit the rhymes.

It may be a good thing ... after our photog gives the former Playmate a beat, she throws down a verse or 2 ... and it's, well, just watch.

Maybe rapping is just a diversion so she doesn't have to talk smack about Holly.
