Ariana Grande has launched her own make-up brand, revealing she struggled to keep the new venture a secret.

The pop star has spent two years perfecting r.e.m. beauty.

"It was so hard to keep a secret for this long!" she told Allure magazine.

The line will debut with eye products like fine-point eyeliner markers and liquid eye shadows, with Grande insisting the eyes are "our main gateways to our dreams, our emotions, our everything".

"They're our main storytellers and sources of communication," she added. "I feel like you can emote more with your eyes than you can articulate sometimes."

And Ariana is not concerned about becoming another pop star with a beauty line, stating, "You can never have enough makeup, just like you can never have enough music."

Asked to detail the inspiration for her new brand, the Side to Side singer told the publication, "I've always sort of gravitated towards the '50s and '60s and '70s for glamour references. I've always pictured myself in a different time period. I've always wanted to wear that makeup, wear that hair, wear those outfits, be those performers."
