As she arrived at a London nightclub, wearing a daring slashed leather dress and grinning widely, it's not hard to see why blonde bombshell Rita Ora is so happy.
Not only did her single R.I.P, featuring Tinie Tempah, reach the number one spot in the British single charts yesterday, she also had her rumoured beau Rob Kardashian on hand to help celebrate last night at Whisky Mist.
The pair avoided being photographed together as they arrived separately, but Rob Kardashian was happy to share his pride with his Twitter followers.

Arriving at the club, the 21-year-old smiled confidently as she showed off her enviable curves in a tight leather dress, with slashed material down each side.
