We may be in the icy depths of winter, but Hollywood celebs are already reaching for spring's hottest beauty trend: orange lips.

The ever-fashionable Rachel McAdams, Chloë Sevigny and Dannii Minogue have all rocked the shade in recent appearances, though the way each has worn the bold hue has differed.

McAdams chose to play it much softer, with a muted sheer coral cream that perfectly balanced out lightly flushed cheeks and her sexily lined smoky eyes. We score this rendition as the one most universally flattering.

Sevigny celebrated the new season of HBO series "Big Love" in L.A. with her co-stars donning a brilliant-orange lip that snapped against her crystal-blue eyes and matching floral frock. A free-spirited blond crop cut splashed a sense of fun over the look.

Minogue also played with a hot-orange lip, but paired it with an equally fiery getup that accented the warm ombre-style highlights of her wavy hair, and also complemented the crispness of the Australian-born actress and singer's baby blues.

If you love that pop of bright citrus, makeup artist Pat McGrath advised us at New York Spring 2011 Fashion Week, "You'll look fresh if you pair it with a squeaky-clean face -- just concealer where you need it, and defined brows with mascara."

Sounds like a formula for screen-siren success to us.
