Lena Dunham, writer and actor in the hit U.S. series 'Girls', has revealed that she's upset at how Rihanna is acting considering everything she has overcome.

The star, who recently won two Golden Globes for her TV show, was interviewed by Alec Baldwin for his radio show 'Here's The Thing' and explained that the Bajan superstar is setting a bad example for both young girls and her fans:

"[Fame is] an amazing thing and it's a platform that you have to take seriously. I used to be really into Rihanna, that popstar, and then it's like - again, I don't want to ever throw stones from my glass house - but I follow her on Instagram and I just think about how many little girls beyond what I could even comprehend are obsessed with Rihanna."

"Like, you know, she left Barbados, she's had this amazing career, she's won a Grammy... She's talented. And then she gets back together with Chris Brown and posts a million pictures of them smoking marijuana together on a bed (pictured below). And it cracks my heart in half in a way that makes me feel like I'm 95 years old."

Dunham added that her own recent rise to fame has made her very aware of what she says in public and how she acts, because she is in a position to influence others: "[I] had to become more conscious about what I say and what I promote, not in a way that stifles me, but just in a way where I realise now that there are 17-year-old girls who come up to me and tell me that the show means a lot to them."
