The sexy singer cannot curb her out-of-control lifestyle, a new report says – do YOU think she is too heartbroken over recent disses from her ex?

Rihanna is beyond hot, but it seems like she is escaping the most recent diss from her boyfriend Chris Brown by partying too hard!

Rihanna, 24, is worrying her friends and family with wild nights out, PEOPLE reports.

“She’s gotten irresponsible with her partying” a source close to her says. “She’s still functioning, but when you add it all up — she smokes and drinks a lot, doesn’t eat properly and has a grueling schedule — you realize she’s bound to hit a wall soon.”

Do YOU think Rihanna is taking out her frustration over Chris, 23, by partying, HollywoodLifers?
