Hollywood Hottest Bachelors: Have a Look Gals

Unattainable can be very sexy. That's the appeal of these men, who have all dabbled in dating famous people but haven't felt compelled to commit quite yet -- leaving women across the world a small glimmer of hope. Keep clicking to see more pics of Hollywood's most eligible (and hard-to-get) hunks.

 George Clooney
George Clooney ages like a fine wine. Full disclosure: Hewas married once, to Mad Men actress Talia Balsam back in 1989. But since then he's vowed never to walk down the aisle again, much to the annoyance of beauties like Lisa Snowdon and Sarah Larson. Will current flame Elisabetta Canalis be able to break the pattern?

Gerard Butler
Gerard Butler's Scottish accent is enough to make any lady swoon. And though he's been linked to A-listers such as Jennifer Aniston, Jessica Simpson and even Lindsay Lohan, this actor insists he's still single and ready to mingle.  

Leonardo DiCaprio
Ladies love Leonardo DiCaprio ever since he stole our hearts as Romeo -- but Leo loves supermodels. More specifically he's romanced Gisele Bundchen and Bar Refaeli, both of whom he dated for a few years before breaking it off. Rumor has it they were ready for something more serious, while he didn't want to commit.

Robert Pattinson
Twilight hottie Robert Pattinson may or may not be dating costar Kristen Stewart, but he's still caught the eye of every other woman in the world -- and not just the tweens. He recently revealed that even the older ladies fawn over him during press events.

John Mayer
John Mayer is another celeb who's become something of a ladies man, having dated Jennifer Love Hewitt, Jessica Simpson and Jennifer Aniston. But who can resist the sensitive musician type? Sigh.

 Chace Crawford
Chace Crawford is just about the prettiest man in showbiz, and his new leading role in Gossip Girl has teens dreaming of Nate Archibald. He's been linked to models Esti Ginzberg and Bar Refaeli, but photogs recently snapped him kissing Twilight star Ashley Greene.

Ryan Gosling
Besides his on-again, off-again relationship with The Notebook costar Rachel McAdams, Ryan Gosling has kept his private life, well, private. All the more reason for hopeless romantics to keep swooning.

Zac Efron
It's quite a feat to have become an eligible bachelor at 22, but Zac Efron has done just that. The High School Musical star's long eyelashes and luxurious hair are the stuff of schoolgirl fantasies -- just as longtime girlfriend Vanessa Hudgens. But Zac's bachelor status isn't likely to change anytime soon: He once said, "I’m not getting married until I’m 40. If ever."

Josh Hartnett
Josh Hartnett can count Scarlett Johansson and Kirsten Dunst among his past loves, but he seems more inclined to get hot and heavy with Hollywood's leading ladies than to walk them down the aisle.

Chris Pine
Thanks to Star Trek, Chris Pine is becoming a household name -- at least among the ladies. His rugged good looks have brought the 29-year-old plenty of attention, and he's loving the perks: a brief past fling with The Hills beauty Audrina Patridge, and a blooming romance with actress Olivia Munn.

Jake Gyllenhaal
Jake Gyllenhaal is one dude who might not be eligible for this list much longer if things keep going well with girlfriend Reese Witherspoon. Despite breakup rumors the two are said to be going strong -- though we have a feeling his fans may mourn a bit if he does choose to settle down.

Shia LaBeouf
Shia LaBeouf can thank a DUI arrest for the birth of his bad boy image, which proved appealing to many of his female fans. The 23-year-old has dated model China Brezner and is currently romancing his Wall Street 2 costar Carey Mulligan, although he's said before that dating costars is something he shies away from.

Kellan Lutz
Twilight heartthrob Kellan Lutz is a former model, so it's no surprise that his chiseled features have made jaws drop worldwide. He's also kept most of his personal life to himself, even denying he ever dated 90210 star AnnaLynne McCord, who he was spotted with all summer long. Hm

Colin Farrell
Colin Farrell is the rebellious type, having completed a stint in rehab for painkiller addiction and even had his own sex tape scandal, so perhaps that's why the 33-year-old favors the unattached life. He was married once to English actress Amelia Warner, but it only lasted less than six months. He just had a baby with current girlfriend Alicja Bachleda-Curus, so we'll see if this bad boy settles down for good.

Ed Westwick
We can't help but be mesmerized by Ed Westwick's dapper Gossip Girl wardrobe, and his chilly prep school attitude on-screen is just sleazy enough to actually work. In real life he's dating his costar Jessica Szohr, but we don't see him settling down any time soon (after all, he's only 22).
