Rihanna and Chris Brown Relationship and Controversial Weed Pics 'Cracks' Lena Dunham's 'Heart in Half,' Not a Good Role Model

It looks like Rihanna has officially rekindled her controversial romance with Chris Brown... and several fellow celebs aren't too pleased about it. During an interview for Alec Baldwin's popular podcast Here's the Thing, star of the hit HBO drama "Girls" Lena Dunham criticized the "Diamonds" songstress for her lack of role model responsibility. The fact that RiRi got back together with her abusive ex-flame and now enjoys posting Instagram pics of the two smoking weed together totally "cracks" Dunham's "heart in half." The 26-year-old actress once looked up to Rihanna... but given the Barbadian beauty's recent shady behavior, not so much anymore.

According to Dunham, Rihanna's ever-growing "bad girl" persona in Hollywood is not something which young fans should try to emulate:

"[Fame is] an amazing thing and it's a platform that you have to take seriously. Which is why sometimes, it's like. . . I used to be really into Rihanna, that pop star, 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. And it cracks my heart in half in a way that makes me feel like I'm 95 years old."

Dunham may be referring to controversial public images such as this one:

This is not the first time Dunham has criticized RiRi's romantic reunion with the "Don't Wake Me Up" crooner - when the duo released a pair of sexually explicit duets back in February 2012, the hit filmmaker tweeted:

@lenadunham: "Rihanna and Chris Brown's new duets make me want to go hide under Gloria Steinem's bed for 72 hours."

As for the "Girls" star and director herself, she hopes that she can eventually prove a better role model for young women - "[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 realize now that there are 17-year-old girls who come up to me and tell me that the show means a lot to them."

And Dunham isn't the first starlet to bash Rihanna's reconciliation with Brown. Country star Miranda Lambert has repeatedly condemned Brown for his past domestic abuse, and "Love and Hip Hop Atlanta" star recently said during an interview - "Why is Rihanna going crazy over this ugly man?!... Rihanna - You're beautiful! You know, you've got your career going. You've got your body going - and he's not that cute! Chris Brown be looking like a crackhead to me sometimes; I'm sorry."
