despite my utter dislike for her, i remember paris hilton mentioning 'prrr' lipglass by MAC.

also, InStyle magazine has several features in every issue where celebrities discuss their favorite beauty products. one feature, in particular, interviews a female celebrity every month about their favorite beauty tips, and then goes through their makeup bag. i think its called 'beauty talk'? lol, i've read instyle religiously for like, 7 years.
