Rihanna 'so smitten with Leo'

Rihanna and Leonardo DiCaprio are apparently already "really comfortable".

The Barbadian singer and the dapper Hollywood star are thought to be dating and were spotted getting cosy at a pre-Golden Globes party earlier this month. They were first seen together on New Year's Eve and have been setting tongues wagging ever since.

According to an insider, the pair are already feeling at ease around each other.

"Rihanna and Leo have a connection. They find each other really attractive and they've been hanging out," the source told British magazine Star.

"They're really comfortable in each other's company."

In the past, 26-year-old Rihanna has attracted rap's bad boys. She briefly dated Drake and had an on/off relationship with Chris Brown, during which he assaulted her in 2009.

Meanwhile, Leonardo is known for his love of models, dating the likes of Erin Heatherton, Bar Refaeli and, most recently, Toni Garrn.

His ex Bar even seemed to give the 40-year-old's new relationship the seal of approval when she was caught on video by TMZ exclaiming Rihanna is "everyone's type".

And for the singer, a different type of man is apparently exactly what she's after.

"Rihanna likes Leo because he's so different from her exes. He's a lot more mature and she's really enjoying spending time with someone that bit older," the source continued.

It's believed Leonardo broke up with 22-year-old Toni towards the end of last year after dating since 2013.
