Rihanna's pals don't like her boyfriend.

The 'FourFiveSeconds' hitmaker's close friends are reportedly wary of her relationship with soccer star Karim Benzema.

The star's pals were also left worried when Karim was seen with Karrueche Tran, the ex-girlfriend of Rihanna's ex Chris Brown.

A source told US' OK! magazine: ''Rihanna can't believe it - she can't get rid of this girl!

''She likes Karim, but she's made it clear she's not going down that road again.''

Meanwhile, Rihanna and the French sportsman are said to be getting on great.

A source said: ''It's taken a long time for the relationship to get off the ground but she says that's what makes it so special. He's the first guy she's actually gotten to know before diving in head first.

''She's been telling people she's never experienced anything like this in her life and that she trusts him like her best friend.''

Rihanna has been ''swept off her feet'' by Karim, with pals thinking the pair are looking at moving forward in their relationship.

A source shared: ''Rihanna seems to have undergone a major transformation. She's gone from saying that she doesn't believe in monogamy at all, to talking about how she just wants to be with one guy.

''It's all because of Karim, he's completely swept her off her feet.''

Whilst another added: ''Secretly I think Rihanna would love a proposal. And Karim has hinted that he's got his eye on a diamond ring just for her.

''But at the moment, she's just enjoying it and seems to be truly happy for the first time in a long while.''
