Are you ready for your close-up?
Deirdre Reynolds puts beauty tips from four of the world's most glamorous women to the test
As no make-up selfies become a thing of the past, beauty junkies here are turning to online tutorials to help re-apply their war paint.
And 33-year-old Kim is just one of the stars to share the secret to her picture-perfect complexion in cyberspace.
"Celebrity make-up tutorials are great for those who already know what they're doing," says top Irish makeup artist Anne Morrissey of The International Make-Up Academy in Dublin.
"The problem is that a lot of girls take them as gospel. When it comes to make-up, there are no hard and fast rules. What works for Kim Kardashian might not work for the next girl. My advice is to take the bits you like and adapt them to suit you."
So should you be logging on to get help before you apply your make-up in the morning?
Here, using only products I already own, I put the beauty advice of some of the world's most glamorous women to the test.
Salma Hayek's glowing visage:
Natural beauty Salma never looks overdone on the red carpet. But the stunning Mexican star still has a few top tips which she imparts on the website for her beauty brand, Nuance. Even going 'au natural' takes a little effort, according to the 47-year-old.
Celeb tip: Salma (47) forgoes heavy foundation in favour of a skin-smoothing primer, tinted moisturiser and just a hint of concealer during the day, and argues that "tinted moisturisers are great [because] it doesn't look like you have a tonne of make-up on".
Our verdict: Not all of us were blessed with lovely olive skin like Salma, and this barely-there base only convinced me there isn't a BB [Blemish Balm] cream on earth that can beat the 'curse of the Celts' – now pass the Pan Stik!
Anne says: "With typically reddish Irish skin, you'd be better off going for a CC [Colour Correcting] cream than a BB cream. Foundation can look just as natural as tinted moisturiser so long as you match your face to your neck."
Heidi Klum's come-to-bed eyes:
She may be considered one of the most beautiful women alive, but even mum-of-four Heidi admits she needs a little help to look her best. In 2011, the German supermodel launched her own lifestyle blog 'Heidi Klum on AOL' divulging some of her tricks of the trade, not least the key to those smouldering peepers.
Celeb tip: Heidi's make-up artist always blends eye make-up on the back of her hand before applying it to the supermodel's face to ensure a flawless finish, and uses white eyeliner on her lower waterline as well as an eyelash curler to really make her peepers pop.
Our verdict: Fab for a big night out, but unless you've got your own glam squad like Heidi, don't make the rookie error of tackling this messy and time-consuming technique when you're already running late like I did.
Anne says: "If you're tired, lining inside the eye is a great, quick way to look more awake. However, I would go for a flesh-coloured pencil rather than white like Heidi, which can look a bit eighties."
Kim Kardashian's killer cheekbones:
New bride Kim is always picture-perfect. So much so that she admits she doesn't know herself without slap: "I feel odd when I don't wear make-up. I don't recognise myself."
In 2012, she famously posted a snap (above) revealing the secret to her killer cheekbones on Twitter, urging fans to: "Try this at home."
Celeb tip: Kim – or rather her make-up minions –trowels pale concealer under her eyes and on her T-zone and a darker shade down the sides of her nose and under her cheeks before blending in her foundation to magically contour her face.
Our verdict: Not for the make-up phobic, but Kim's slap-happy technique definitely made my chubby cheeks look more chiselled – now I just need her bank balance to stock up on more of the stuff!
Anne says: "You can achieve the same look as Kim without using as much product: simply sweep bronzer or foundation that's two to three shades darker than your regular foundation in a number 3 shape along your forehead, cheekbone and jawline."
Drew Barrymore's perfect pout:
As Hollywood's queen of romantic comedy, Drew's lips always look kissable. Now The Wedding Singer star has spilled the secret to her pillowy pout, among other beauty cheats, in weekly 'Tip Tuesday' videos for her cosmetics brand Flower on www.flowerbeauty.com.
Celeb tip: After priming her lip line with a little foundation, Drew adds some oomph to her kisser by patting a hint of white eyeshadow onto her Cupid's bow and slicks on some lippie.
Our verdict: While illuminating my upper lip helped create the whole bee-stung thing that the actress is famous for, the foundation also made my lipline disappear, so in the end, I quite literally 'Drew' it on.
Anne says: "Applying lipliner after your lipstick or lipgloss helps stop the colour from bleeding and makes it easier for those who don't have perfectly symmetrical lips like Drew to apply."
