Who are Hollywood's hottest men dating?

Being single just isn't cool anymore.

We take a look at the women Hollywood's hottest men will be romancing this Valentine's Day!

George Clooney -- Stacey Keibler

Former WWE wrestler and all around leggy goddess, Keibler is the latest in Clooney's line of insanely hot blondes -- a list which includes several known porn actresses. Clearly, the man who can have any woman he wants has a type.

He's had quite a stellar list of supermodel beauties -- Gisele Bundchen, the magnificent Bar Rafaeli, actress Blake Lively and now Madalina Ghenea.

A striking 22-year-old Romanian model, Ghenea is best known for her appearance on Dancing With The Stars.

He might be the thinking woman's sex symbol, but current Hollywood it-boy Gosling has been in a relationship with actress (and Calvin Klein underwear model) Eva Mendes since September 2011.

His previous girlfriends have also been actresses: Gosling dated Sandra Bullock in 2002 and Rachel McAdams from 2005-2007.

Green Lantern star Reynolds is a veteran of high-profile relationships, having first been engaged to Alanis Morisette for three years and then being married to Scarlett Johannson for three years.

For the last three months, however, Reynolds has been seeing Gossip Girl star Blake Lively.

Remember the journalist in the last season of 24, who was in love with Anil Kapoor? Well, that's Jennifer Westfeldt, who's been girlfriend to television's Don Draper since 1997.

The two of them have even appeared in Gap advertisements together.

Back in 2006, Hangover star Bradley Cooper married actress Jennifer Esposito, only to file for divorce a year later.

In 2010, however, it was learnt that the actor had been dating actress Renee Zellweger for over a year. While People magazine claimed last summer that the couple had split up, no official confirmation followed.

Lord Of The Rings actor Bloom started dating devastatingly gorgeous Victoria's Secret supermodel Kerr back in 2007, after he had broken up with actress Kate Bosworth a year before.

Bloom and Kerr got married in 2010, and she gave birth to their son, Flynn Christopher Blanchard Copeland Bloom, in January 2011.

He's been around, he has. Affleck's dated Gwyneth Paltrow, Jennifer Lopez -- his relationship with whom was dubbed 'Bennifer' by the tabloids -- and then finally settled down with Garner in 2005.

The couple has two daughters and is expecting a third child this year -- and all this without Affleck having to give up the Bennifer tag.

Damon's first Hollywood romance was with his Good Will Hunting co-star, Minnie Driver. He then dated Winona Ryder for two years, and then, while filming the 2003 film Stuck On You, he met the Argentinian Luciana Barroso in Miami where she was working as a bartender.

The couple have three daughters together and live in Manhattan.
