4.) Isla Fisher
Why You Know Her: Isla Fisher is best known for her role opposite Vince Vaughn in The Wedding Crashers, but she's most recently been on the silver screen in Confessions of a Shopaholic.
What Makes Her So Sexy: Isla is the answer to "What Guys Want". Sure, she's adorably cute and wickedly funny, but she conveys a strength and character that makes guys swoon. Also, she's a redhead, which most of the guys in our office agree is her best asset.
LoveStage: Engaged to Borat actor, Sasha Baron Cohen. They have a daughter named Olive.
5.) Julian McMahon
Why You Know Him: The scandalous son of Australia's former Prime Minister Sir William McMahon, McMahon is best known for role as Dr. Christian Troy on FX's Nip/Tuck.
What Makes Him So Sexy: McMahon's role on Nip/Tuck leaves nothing to the imagination. Not a week goes by when he isn't bedding some sultry siren in a variety of outrageous positions. Still, it was his turn as the half-demon/half-human Cole Turner on Charmed that really won our hearts. McMahon showed off a decidedly tender side while wooing and losing his true love Phoebe (Alyssa Milano). All that pain, anger, romance, undying love, not to mention passionate kisses, is why we'll always come back for more McMahon. Considering his active social life (past loves include Danni Minogue and Shannen Doherty), we're guessing he's just as popular with the ladies off-screen.
6.) Portia de Rossi
Why You Know Her: She starred as clueless heiress Lindsay Bluth Fünke on cult-fave Arrested Development.
What Makes Her So Sexy: Portia de Rossi is like a checklist for sexy women. Tall, blond, beautiful, funny. Check, check, check, and check. Yet, it's who she is in real-life that we find sexiest of all. After being outed in 2004, de Rossi has discussed her sexuality with a frankness and openness that few have matched. Add to that her passionate commitment to charities (Locks of Love and African AIDS Relief, among others) and you've got a recipe for one of the hottest women on the planet.
