Fashion fans and beauty junkies alike want instant gratification—immediate insider beauty news, tips, trends and expert commentary as it’s happening backstage from the upcoming Spring/Summer 2009 fashion shows.

As a result, the MAC Cosmetics Pro Team of makeup artists—fixtures backstage at over 175 fashion shows worldwide—will use Twitter this season to give real-time updates about their experiences working behind the scenes at the upcoming New York, London, Milan and Paris collections.

Twitter is a micro-blogging service available online and via any mobile phone. People “tweet” each other on their computer or phone through quick, frequent exchanges limited to 140 characters. Now, for the first time ever, diehard fashionistas and makeup lovers around the world can connect with MAC senior artists backstage, in real-time at the season’s hottest shows to learn the scoop on the looks they’ll be seeing on the runway before, during and after it happens.
