Was their hatred in the name of more PR?

The Hollywood News reports:

A Simple Life stars Paris Hilton and Nicole Richie are reportedly going to 'make up' live on air on the David Letterman Show in the US. The duo have been at loggerheads since before the last series of the hit reality show. Rumours are that the reason for the rift between the two was because Richie screened Paris's infamous sex tape at a party. Tut-tut.
Anyway, Letterman apparently made the offer to the two to appear on a September show to kiss and make up.
A fifth series of The Simple Life is also planned for later in the year.

Boo hoo. I loved them hating each other. It was fun. I loved how cold Nicole was about the whole thing.

Paris shouldn't have taped herself having sex - so what if Nicole had a viewing of it at a HUGE party.
