We love both of the ladies' looks, but we have to point out Stefani's volumised mane - the backcombed style definitely adds two or three inches to her height. She hasn't quite reached Cheryl Cole's beehive level yet but Gwen does make Winslet's do look rather boring by comparison.
Let us know how you rate their A-list style and shop their looks below:
Take a look through Gwen's beauty evolution below:
Beauty Evolution - Gwen StefaniSeeing her perfect light gold locks and seemingly tattooed on red lipstick day after day, it's easy to forget that Gwen Stefani's taste hasn't always been so classic. Her not-so-secret beauty past includes bindis, braces and blue hair. From "Just A Girl" to a global superstar, Ms. Stefani has come a long way, baby!

Breaking onto the music screen as the mid-drift baring front woman of the Orange County ska band, No Doubt, Stefani's look was one part "homegirl", one part punk rock chic, and one part Indian goddess.
Taking her love for bindis just a little bit too far, Gwen went exotic at the Billboard Awards.
Still rockin' the binidis, the No Doubt songstress created a rad rave-revival look by dying her hair blue.
A self-confessed makeup addict, Stefani told InStyle magazine "I haven't seen my real hair colour since ninth grade!"
Still pink, Stefani went light on the makeup, letting her braces make the statement. No doubt, teen girls everywhere thanked her for making metal mouths so chic!
Looking like Baby Spice gone bad, Stefani let her hair down (and a lot of hair that wasn't hers!) at the VMAs.
Matching her makeup to her So-Cal outfit, Stefani let her inner home girl shine pairing nude lipstick with dramatically contrasting dark lip liner.
Ever wondered where she got her flare for makeup? Before Stefani made it big in the music biz, she manned a M.A.C cosmetics counter to pay the bills.
In a clear case of life imitating art, Stefani walked the red carpet looking like the reincarnation of her character in The Aviator, Jean Harlow.
