Rihanna and Ellie Goulding have sparked duet rumours after swapping phone numbers.
The two singers were performing at the V Festival in the UK over the weekend.
Rihanna reportedly invited British songstress Ellie backstage for a gossip in one of her 15 dressing rooms.
The pair apparently got on so well that they exchanged numbers and there are rumours they are keen to collaborate.
Ellie was the only artist allowed to watch Rihanna's highly-anticipated performance from the side of the stage.
"It was incredible watching Rihanna side of stage. All of the men around me had to cross their legs watching her," she told British newspaper The Sun.
Ellie has attracted a host of celebrity fans since she performed at the wedding of Britain's Prince William and Catherine Middleton earlier this year.
Rihanna and fellow V Festival performer Eminem left the venue in England in a private jet when the rapper had finished his set.
Rihanna has been enjoying a vacation on a £200,000-a-week luxury yacht since her performance at the weekend.
The stunning star set sail on the luxury vessel off the coast of the French Riviera, showing off her honed figure in a multi-coloured cut-away swimsuit. The singer sent a speedboat out to collect friends from nearby St Tropez and looked thrilled when she saw her pals approaching.
