How did the girls of the new girly comedy L!fe Happens get their perfect pouts? Celebrity makeup artist Amy Nadine headed up the makeup department for the new flick—which Krysten Ritter co-wrote and stars in alongside Rachel Bilson and Kate Bosworth—and turned to Tarte LipSurgence lip tints, a stain that improves lips’ moisture ($24 at tartecosmetics.com). “It was really important to us that the girls were young and attainable and looked like they did their makeup themselves,” Ritter told InStyle.com exclusively, adding that this was the only product all three stars wore during the entire film. “We didn’t want them to look overdone and wanted each to have their own distinctive look.” Ritter’s character Kim switched off light mauve Enchanted, deep berry Moody, and blood red Lust; Bosworth’s straight-shooting relationship columnist Deena went for the cool-tone, matte-finish warm rose Hope; and Bilson’s virginal girl-next-door Laura went for light pink Lucky. Check them all out in L!fe Happens, which opens in limited release today and nationwide May 3rd.
