PHOTO: See The 20 Worst Celebrity Self Photos Ever [A Must Look]

STARS feed off attention like the rest of us thrive on oxygen.

So it's no wonder that the celebrity 'selfie' has become a force of nature.

Gurning, giggling or posing with owls, the big names love to take their own picture and then share it with the world.

But some shots are sexier than others...

Join us now as we take you through 20 of the worst ever celeb self-portraits on Twitter and Instagram.

1) Kim's sunburn

Kim Kardashian yet again shows her burning ambition to stay famous with this Twitter snap.

Stock up on the factor 30 next time, KK.

2) Justin's park life

Justin was clearly hoping to show once and for all that he's a GROWN-UP with this beer-toting shot.

Instead, he looks like a young scally bunking off school to get boxed on Tesco Value tinnies in the park.

3) Demi's back

Nope, we don't get it either. Demi Moore flaunts a bony shoulder and a nice basin in this shot.

Bring back the bikini snaps, D!

4) Amanda's cry for help

Remember Amanda Bynes from goofy teen flick She's The Man? This is apparently her.

Yep, we're pretty shocked too.

5) Madonna's cocktail face

We have now come full circle - Lady Gaga found fame by copying Madonna and now Madge makes a last-gasp effort to look like Gaga.

Clearly in need of 40 winks and a better underwire, the Material Girl does not give good selfie.

6) Oprah's bouquet

Who doesn't love a hydrangea, eh?

But there is still something bonkers about Oprah Winfrey's decision to give them centre stage in this selfie.

7) Kanye's tough call

Kanye is, like, such an inscrutable star even when dialling for a pizza.

Nice one, tough guy.

8) Brooklyn's derp face

Showing the supreme confidence of a beautiful woman, Brooklyn Decker pulls her 'ugliest' face possible for the camera.

Guess she'll take the haters' comments on the chin(s).

9) Hilary's baby

Clearly not ready for his close-up, Hilary Duff's son Luca shows his disgust for the selfie trend.

Good lad.

10) James's strip tease

James Franco clearly understands that one must suffer to be beautiful.

We assume these are pore-cleansing strips from Boots, no?

11) Niall's sleeping mate

Nothing says friendship like taking a sneaky shot of your mate asleep - and then sharing it with 11million people.

Irish TV presenter Eoghan McDermott must have been chuffed to bits with 1D's Niall Horan.

12) Ricky's moobs

Ricky Gervais looks suddy awful in this faux-sexy bathtime snap.

A soap star he ain't - but he did give us a laugh.

13) Kim's feet

Ouch! It's not just Kim Kardashian's head that's swollen these days.

The pregnant star showed off her feet on Twitter last week with the caption: “Swollen feet or a new Givenchy tattoo?"

Someone give this woman a pair of Converse pronto.

14) Lindsay's arm workout

1) Fumble with iPhone

2) Hold pooch aloft with one hand

3) Pull a duckface

4) Snap the hell out of yourself!

Result? Blurry weirdness.

15) Rihanna's swearfest

Proving once again that only the coolest people eff and jeff, Ri-Ri sports sweary(ish) clothing for a snap.

When I grow up, I want to be just like her.

16) Miley's horseplay

Nothing says Hollywood A-list like a horse-faced onesie, eh?

Engaged star Cyrus captioned these shots: "It's a onezie PARTY (of one)"

Where's your groom, love?

17) Lady Gaga's prayers

It's very nice that Gaga prayed for the victims of the Brazilian nightclub fire.

But we probably didn't need to see her sans warpaint doing so.

18) Katie's wake-up call

If locks could kill, eh!

Katie Price shows she's due a trip to the salon in this staggering Twitter snap.

19) Chris' wacky baccy

Any fool can smoke a joint in Amsterdam - but it takes a real class act like Chris Brown to smoke three.

Proof - if more were needed - that this man is an idiot.

20) Cara's owler

Not content with being a looker, Cara Delevingne insists we think she's kerazy fun too.

She tweeted: "I am Dr Do-owlittle... Look into my owls!!"

Sigh.
