It's the day of hearts where almost everyone in the whole planet decides to show their undying passion and affection to the members of the opposite sex. So a few celebrity couples may be spending it happily ever after like there's no such thing as tomorrow, but there are a few bitter roots that'll be spending Valentine's Day all alone.

Who are these celebrities?

Though it won't be much of a surprise if she spends it with another man, Kim Kardashian who had gone through a messy divorce to NBA player, Kris Humphries, will be spending this year's Valentine's Day all alone. Her hunky husband won't be around to answer to her every whim but knowing the "Keeping up with the Kardashian" star, Kim might have a few numbers on her phone to spare.

"New Girl's" it star, Zooey Deschanel won't be serenaded this year by her hubby Ben Gibbard from 'Death Cab for Cutie' as the two had recently just divorced. Though rumor has it, Zooey, is being hit on by another divorcee, Russell Brand.

Russell who has also been recently divorced from singer, Katy Perry, won't have any luck wooing his ex-wife's doppelganger. Everyone knows Zooey isn't one cheap fish in the sea. Katy on the other hand may be spending this year's Valentine's Day alone but she's got her single and not to mention equally hot best friend, Rihanna, to accompany her.

Another divorcee who might be skipping out of the love celebration is top model, Heidi Klum. Though there's no word if she'd be meeting up with ex-husband, Seal. However, the possibility of them joining up for the sake of their four kids is quite high.

One last divorcee who is most likely to spend it at another hospital or rehab center is Demi Moore. Her divorce with actor, Ashton Kutcher, has definitely taken a toll on the actress' health and signs point out she's nowhere near ok to celebrate a Valentine's Day.

So the divorcees are keeping their noses clean this year but how about a few celebrity couples who've been dating for a year?

Rock star princess, Avril Lavgine, has missed out on her chance of a "Happy Ending" since her recent spilt with Brody Jenner. Though the two have an on and off and on again relationship, fans and the media doubt they'd make any plans for this year's Valentine's Day.

As for "Glee" star, Chord Overstreet, he's singing a new tune but the actor hasn't been spotted out with a replacement unlike his ex-girlfriend, Emma Roberts, who was spotted stepping out of a restaurant with another blonde dude.

Taylor Swift, the country crooner who claims she's unlucky in love, might be spending this year's Valentine's Day alone but who knows if her co-star, Zac Efron, might ask her out.

If fans could have their way, they'd be spending each Valentine's Day with these lonely celebrities each year on February 14. Here's to hoping these celebs don't make it to the list of lonely A-listers next year.
