Rihanna made a bold statement on Tuesday night at the launch of her new fashion collection in London.
The global superstar dressed her lips in blue lipstick to go with a sexy androgynous look complete with a black and white fur varsity jacket, see-through shirt and skinny metallic jeans.
And thanks to the party celebrating her new autumn/winter collection for River Island, Rihanna, 25, got the chance to hang out with her model pal Cara Delevingne.

Calling out to her British fans, Rihanna tweeted on Tuesday: 'UK Navy, I'm in London today launching the Autumn #RihannaforRiverIsland range.'
The Bajan singer hosted the cocktail event to mark her second sartorial outing for the high street retailer, held in the penthouse suite at the Dorchester Hotel.
The party then moved on to Cut restaurant in Mayfair where the fashionable elite continued their evening.
But as Rihanna - who modelled items from her new range - left the upmarket hotel she made sure to pose with some fans, and give one lucky police officer a little memento in the form of a yellow beanie hat with 'Ri Ri' written on it.

Cara Delevingne also wore pieces from the River Island collection - which will appear in selected stores this week - inspired by urban street wear, as she joined Rihanna for a glass of wine at the launch.
'I literally designed everything I want to wear — exactly how I want to wear it,' the popstar said in a promotional video.
Rihanna was also in town for the city's Fashion Week where her costume designer Adam Selman made a provocative catwalk show debut last Thursday.

Adam also lent his expertise to the star's inaugural River Island collection.
Speaking to MailOnline about his show, which featured heavy on the lingerie, he referenced his famous client.
'Rihanna is definitely a muse for me, it’s no secret, but I didn’t necessarily think of her when I was designing this,' he said.
