It wasn't a very happy Valentine's Day for Rihanna yesterday.

The singer cut a lonely figure as she spent the evening without her on-off boyfriend Chris Brown.

Chris Brown was no where to be seen as Rihanna partied on Thursday night

It comes just after reports emerge that there is trouble between the recently reunited pair.

On Wednesday night, the pair were seen partying at the same club, but spent the whole evening separate from each other, with Rihanna refusing to be anywhere near her on-off love.

According to MailOnline, who had spies inside the Playhouse Nightclub in Los Angeles on Wednesday night, Rihanna "refused to sit with or even near Chris, and when Chris noticed she was there he made a huge show of rubbing his presence in her face," the source said.

The pair later then left the club separately too.

The reports of trouble between the pair is likely to please RiRi's former bestie Katy Perry, who has fallen out with the star over her rekindled relationship, and stayed away from Rihanna at Sunday's Grammy Awards.
