These celebrity duos share the same first name -- but their good looks are all their own!
jennifer lopez vs. jennifer aniston
Talk about 40 and fabulous! Hollywood veterans Jennifer Lopez and Jennifer Aniston put those 20-something starlets to shame with their wisdom, experience and stunning beauty.
kristen stewart vs. kristen bell
We're not sure if Snow White and the Huntsman star Kristen Stewart is "the fairest of them all," but she's definitely pretty -- especially in those rare photos when she's actually smiling! However, blonde babe Kristen Bell offers some healthy competition.
bradley cooper vs. brad pitt
If only all Brads were this beautiful! Brad Pitt has been making us swoon for decades, but Bradley Cooper is the reigning Sexiest Man Alive. Which dapper dude is more drool-worthy?
kate middleton vs. kate hudson
It's actual royalty versus Hollywood royalty! How does the Duchess of Cambridge stack up against actress Kate Hudson in the looks department?
ashley greene vs. ashley olsen
As a vampire in the Twilight movies, Ashley Greene's physical appearance is flawless. But pint-sized fashion mogul Ashley Olsen proves that good things come in small packages!
ryan gosling vs. ryan reynolds
We're guessing the name Ryan had a popularity surge after these two hit the scene. After scoping out their chiseled six-packs, we couldn't possibly choose between Ryan Gosling and Ryan Reynolds -- but you can!
jessica alba vs. jessica biel
Jessica Alba and Jessica Biel both have talent, killer style and a seriously hot man in their lives. Which dark-haired beauty is prettier?
jason bateman vs. jason segel
A good sense of humor is always attractive -- which is why this funny duo is so cute! Horrible Bosses star Jason Bateman has a sweet smile, but How I Met Your Mother's Jason Segel has the height advantage.
eva mendes vs. eva longoria
Eva Mendes' alluring appearance has earned her a spot in Ryan Gosling's arms. (Lucky lady!) But show-stopper Eva Longoria can certainly hold her own on the red carpet.
justin timberlake vs. justin bieber
They've both got sultry songs, steamy dance moves and screaming female fans. And while Justin Timberlake has 13 years on The Biebs, their looks are more closely matched.
emma stone vs. emma watson
The Help star Emma Stone and Harry Potter's Emma Watson are both known for their enviable wardrobes -- but is it the American or the Brit who wins your vote?
zoe saldana vs. zooey deschanel
We love Zoe Saldana's edgy-glam look almost as much as Zooey Deschanel's quirky-cute style. Is it the Colombiana star or the New Girl actress who turns more heads?
josh duhamel vs. josh jackson
These scruffy-faced stars are both smoldering. But would you rather cuddle up to Josh Duhamel or Joshua Jackson? (We promise not to tell their better halves!)
katy perry vs. katie holmes
Katy Perry is bold and flashy, while Katie Holmes is refined and classic. Holmes is a married mama, and Perry is single and ready to mingle. They're as different as night and day, but they have good looks in common!
kate upton vs. kate bosworth
After seeing her dance, most men might choose Sports Illustrated model Kate Upton -- but actress Kate Bosworth has good looks, too!
taylor lautner vs. taylor kitsch
Team Jacob or Team Tim? Twilight star Taylor Lautner and Friday Night Lights hunk Taylor Kitsch both have hoards of female fans, but where does your loyalty lie?
john krasinski vs. john mayer
John Krasinski can make you laugh with his sarcastic quips, while John Mayer can make you swoon with his sweet songs. Is it the star of The Office or crooning bad-boy who looks the best?
khloe kardashian vs. chloe sevigny
Reality star Khloe Kardashian is tall, curvy and dark-complected, while Big Love star Chloe Sevigny is petite, slender and fair-skinned. Which unique beauty gets your vote?
will smith vs. will arnett
Hot dad alert! Let's hope Men in Black star Will Smith and Up All Night's Will Arnett both pass on their humor (and their hotness!) to their little ones.
