Singing sensation Rihanna spent her evening celebrating with a well-deserved slice of cake as news broke that the Barbados-born beauty's first make-up line was flying off the shelves.
The collection which is collaboration with MAC make-up features a red lipstick called RiRi Woo – a take on the cosmetic company's bestselling Ruby Woo – reportedly sold out within three hours after its launch.

The Diamonds singer puckered up her own lips that evening in a photo that showed the party's lipstick-shaped cake which the star posted onto Twitter.
The singer-come-cosmetic queen then took a picture of herself kissing the cake, which was the same colour as her RiRi Woo shade, before grabbing a knife to cut off a sizeable chunk for eating.
Despite the sweet treats Rihanna, 25, looked slender in her sultry two-piece jersey outfit. Wearing a dark grey crop top and a slinky matching skirt tied at the waist to show off her toned legs, Rihanna complemented the look with a pair of pointed beige heels.
In an interview with Women's Wear Daily, Rihanna described that her new beauty deal with New York based franchise was "a no brainer," disclosing that that MAC products are already her stage make-up essential.
"When you think of make-up, the brand that pops into your mind – for something legit – is MAC," Rihanna explained. "Whatever colour you want, it's like 'Let's go to MAC.' I've been using MAC on tour for such a long time it was a natural fit for me."
After the initial sell-out success of her first MAC feature, Rihanna also informed fans on the social media site that the limited edition lipsticks would be re-issued in June.
More than just a face to front the brand, MAC say Rihanna's involvement "is a true, organic collaboration based on mutual admiration and respect" and the parternship is set to continue over the next year.
The rest of the RiRi Hearts MAC will launch in four seasonal collections over the coming year and will also include eye shadow palettes, brushes and false lashes.
