Pop star went wild at the bash as she celebrated creating her own cosmetics collection

RIHANNA got behind the decks to party in a purple mini-dress at the launch of her new beauty line.

The pop star went wild at the bash in London last night as she celebrated creating her own cosmetics collection.

Umbrella singer Rihanna, 29, looked lovely in a lilac gown which showed off her long, lean legs.

The singer did twirls for snappers outside the event as she showed off the pretty baby doll gown, teamed with sexy high heels and chunky bracelets.

The launch of her FENTY Beauty line, which is titled after her full name Robin Rihanna Fenty, was held at Harvey Nichols in Knightsbridge, West London, where the range will be stocked.

After introducing the line at the event, Rihanna was able to celebrate properly with a big party.

The well-known party animal was pictured having a wild time at the bash and even taking over the decks to DJ.

Rihanna waved her arms in the air as she pumped out her favourite tunes for the crowd.

Other guests at the bash included TV presenter Sarah-Jane Crawford, singer Tallia Storm, broadcaster Maya Jama and musician FKA Twiggs.

Rihanna has been praised for her work on the new line, which features a massive 40 shades of foundation so make-up fans can find a shade to match their skin tone.

During the bash, the Grammy Award winner was also seen showing off her own make-up skills by giving guests makeovers using her products.

As well as foundations, the collection also features eye-shadows, lip sticks and even male-up brushes.

Fans have gone wild over the expansive collection and many shares are already sold out just days after the range went on sale online.
