Los Angeles, Mar 26 (IANS): Rihanna has reportedly been advised to take rest and stop partying if she wants to fulfil her touring commitments.

"She was forced to cancel two concerts in Baltimore and Boston after coming down with laryngitis. She has since resumed the tour and promised to reschedule the cancelled shows," the source added.

"Rihanna is scared.She loves to smoke, drink and stay up late. Her body was bound to need a break at some point. She's now on a mission to start looking after herself," said the source.

Insiders also claim that Rihanna recognises her relationship with Chris Brown isn't having a positive influence on her.

"Rihanna has received death threats, verbal attacks and has fallen out with some of her best friends recently, including Katy Perry. This has taken a huge emotional toll," the source added.
