How does grammy nominee Katy Perry make sure her lipstick stays in place when she’s performing? She follows this no-fail routine: Fill the entire lip area with lip liner; go over it with a matching lipstick color (her current favorite is a bold crimson shade called No. 54 by Nouba); blot with a tissue; and set the color with powder. “It’s simple, but it always works,” says Jake Bailey, the “Teenage Dream” singer’s makeup pro. “I also use lip stains but never gloss. It can run off on the microphone, or her hair gets caught in it.” The same beauty rule applies on the set of Fox’s hit musical Glee, which nabbed two Grammy noms. “Lip stains are long-lasting and not drying or sticky — we can’t have hair sticking to lips during the dance numbers,” says Eryn Krueger Mekash, head of makeup on Glee, who uses Tarte Lip Stain in Envy on Dianna Agron and Lea Michele. And don’t make the mistake of overapplying lip color. “You’ll end up with lipstick on your teeth,” warns Bailey, who recommends using a lip brush or your fingertip to blend in the color evenly. Now you’re ready for your close-up.
