Rihanna is 'obsessed' with Leonardo DiCaprio, according to reports.

The Stay singer was rumoured to be dating the Titanic actor earlier this year. While it seemed like things had cooled off in recent weeks, it's now been claimed that the 27-year-old has decided to pursue the actor once again.

'Rihanna went running back to him shortly after Coachella. She just couldn't get over him,' a source told InTouch Weekly, 'She's still really into him.'

The couple reportedly rang in the New Year together in St Barts. The pair were later photographed together at Rihanna's 27th birthday party, and the source believes the singer is hoping it's a sign that the 40-year-old will commit wholeheartedly to their relationship.

'Right now, they pretty much just hook up and go to each other's houses late at night, but Rihanna's holding out hope that Leo will eventually commit,' the added. 'She's obsessed.'

While neither star has spoken about their rumoured relationship, the latest reports seem to contradict past claims that the Barbadian beauty ruled the roost.

'Rihanna is by far the most independent woman Leo has ever dated. He tends to be the boss, but with Rihanna it's different,' a source told British magazine Grazia. 'They're equals and it's a good change for him."

Leonardo has built a bit of a reputation as a ladies' man, having previously dated supermodels including Bar Refaeli, Toni Garrn and Gisele Bundchen. Meanwhile Rihanna had a high profile relationship with fellow singer Chris Brown, which finally ended in 2013.
