On Saturday night, Heidi Pratt's older sister Holly Montag celebrated her birthday at a party in Los Angeles wearing bright pink lipstick. Last month we saw her at another Hollywood party with glossy, brownish-nude coloured lip gloss, and back in June, she really rocked the red carpet wearing showing off her megawatt smile in shiny red lipstick at a 2009 BET Awards party. Out of these very different lip looks below, which do you favour on Miss Montag?
