Casey Donovan shares before-and-after-makeup photos, looks flawless both ways

Casey Donovan is keeping it real.

The 29-year-old singer is currently promoting her new album, Off the Grid & Somewhere In Between, and shared some before-and-after makeup photos while popping by the ABC studios.

"Before.....And After…," Casey captioned the slideshow of Instagram images, which showed her pulling a face without a makeup, followed by another selfie that showed her looking bemused with a full face of makeup.   

She added, "Almost performance time on #TGIF With Richard Glover on ABC Radio."  

Her 38.1K Instagram followers were quick to sing Casey's praise, with many complimenting her "natural beauty".

"You don't need makeup Casey," one fan commented.

While another wrote, "Gorgeous girl...before AND after!"

This year has been a busy one for Casey, who rose to fame after winning the second season of Australian Idol in 2004.

In March, she returned to her reality roots claiming victory on the game show, I'm A Celebrity… Get Me Out Of Here. Throughout her six-week stint in the African jungle, the reality star hit the headlines after it was revealed she had lost 17 kilos on the show.

The witty singer also kicked her smoking habit in the jungle and confirmed to The Project in May that she's since been able to stay "off the darts."

And it's been all systems go since her I'm A Celebrity win, with the singer-songwriter releasing new music after a seven-year hiatus from the industry, as well as starring in Coles' irritatingly good ad campaign, "Down, Down".
