The Orange is the New Black star is taking on a role as the cosmetic company's Most Addictive New Vice, which will see Ruby "keep on rocking (Urban Decay's) world and spreading the gospel of (its) self-expression, addiction to colour, and 'beauty with an edge'", according to a press release.

"Urban Decay believes in supporting individuality and personal self-expression - two values I hold very dear - because everyone deserves the freedom to explore their personality and discover their true selves," the 29-year-old says in a statement.

Ruby's new venture shouldn't come as a surprise to devotees. She has previously admitted she is a big fan of Urban Decay and regularly uses its Perversion Mascara and Naked Flushed Bronzer/Highlighter/Blush Strip in her everyday life.

"I can't go outside the house without lip balm, mascara and eye brows are really important to me," she told PeopleStyle. "I'm not sure why I've got such an affinity for them, but they're kind of a go-to for me."

Ruby isn't the colourful cosmetics firm's first celebrity ambassador - they also teamed up with Gwen Stefani last year (15) to launch her own line of bold lipsticks, eye shadows, and eye liners.

The news emerges just two months after Ruby scored her first brand partnership with designer label Denim & Supply Ralph Lauren.

She and model Hailey Baldwin are fronting the global print and digital campaign for the company's new spring collection. The duo also feature in 15-second short films, which have been released on the brand's Instagram.com page in a four-part series.

"I love the fact that (the brand) is using Instagram to create these mini films, these little 15-second cinematics, because I definitely get a lot of the information, my inspiration and style inspiration from social media platforms, and on Instagram especially," Ruby told PeopleStyle in January (16). "And I think that people's attention spans are much shorter these days, and you're less likely to captivate or hold people's attention for that long. But the way we've done it, I really think people are going to enjoy it."
