Remember the last time Paris Hilton went to see David Letterman? He asked about her stint in the slammer -- and she wasn't too stoked about it.

But TMZ has learned that Dave's getting another shot with Princess P, and that she'll be a guest on the show on Friday, Feb. 1. It'll be the sixth time she's been on Dave's show -- and her first since that memorable appearance on Sept. 28.

Back then, when an audience member yelled out, "I love you Paris!", Letterman quipped, "Is that somebody you met in prison?" As the audience cackled, Paris moaned, "Now you're making me sad that I came." Not too sad, apparently, to return.
