Selena Gomez has more than 89 million followers on Instagram, so naturally she won't post just any photo to the platform. It turns out that she relies on the same editing and clever filtering as anyone else to get her sultry selfies and behind-the-scenes tour snaps just right.

The Good for You singer's makeup artist Hung Vanngo has revealed what goes into taking and editing Selena's flawless selfies – and it's easier than we thought.

Rather than relying on Photoshop or other apps to fine tune her images, Selena first takes time to think about make-up, lighting and setting to capture her best angles before simply using a filter to give her photos a gorgeous finish.

CELEBRITY TIPS FOR THE PERFECT INSTAGRAM SELFIE

Hung shared a before-and-after glimpse at one of Selena's selfies, with an "Instagram photo 101" step-by-step guide to the edits used.

"Here is an unedited & edited versions of an Instagram photo. #brightness #contrast #warm #saturation #color #vignette #sharpen… #TheSkyIsTheLimit Enjoy!!!" he wrote.

Selena looked gorgeous in both snaps, but the finished result is brighter and more striking, with her hair appearing a richer auburn shade.

The 23-year-old has been experimenting with her hair and make-up during her Revival World Tour, and has shown off the results with a number of beautiful selfies. Most recently Selena had a fringe cut into her long wavy tresses, and debuted a new colour, choosing lighter brown hues with hints of blonde for a summer-ready makeover.

There's no doubt that Selena constantly has fans coveting her glossy, textured hair, and the singer recently delighted her fans when she revealed her unusual trick for achieving the look.

"I don't wash my hair every day, which may sound gross, but it's actually really bad for my hair," she told Allure. "Some of my best friends actually can't go more than maybe two days without washing their hair, and for me, I give my mom and my dad all the credit, because I have thick hair, so it gets better the less I wash it."
