Rita Ora feels "empty" without lipstick on.
The 'How We Do' hitmaker - who is known for her signature red pout and blonde locks - has confessed she hates going out without colour on her lips as she feels her look is incomplete.
Describing her beauty regime, she said: "Putting on moisturiser and looking after your skin is so important, but I love makeup too. I've always been about the lips and the lip colour. Without a lip colour I just feel empty.
"My favourite beauty tips are using lipliner underneath lipstick to make it last and, it's an old one, but sleep is so important - its fixes everything."
The 24-year-old beauty also labelled her mum, Vera, as her favourite "beauty icon" and added she is inspired by the "masculine" but "sexy" looks of the '90s.
She explained to The Sunday Telegraph newspaper's Stella magazine: "My mum is my biggest beauty icon: she is a big skincare fan and has always kept to her regime, so she inspires me to keep to mine.
"The whole 1990s era inspires me, as it was all about women being sexy but masculine at the same time and I love the exaggeration of glamour during that era."
Rita added she can be a little OCD when it comes to taming her brows and is lucky to have found a shape she can stick too.
She said: "I love anything to do with brows, too, and I've always been a bit OCD about them: I tweeze whenever I get the chance. It's all about finding the right shape for you, sticking to it and colouring it in."
