Rihanna Alarms Fans After Tweeting She 'Starved' Herself For Esquire Photo Shoot

Don't make us worry RiRi!

The curvaceous singer has given her many adoring fans some major cause for concern, after Tweeting she had to "starve" herself in preparation for an upcoming Esquire magazine photo shoot.

The 23-year-old singer Tweeted on Wednesday:

"#RihannaNavy I shot my first cover for Esquire yesterday with Russell James #rockstars*** Not much preparation for that besides wax+starve!!"

Yikes! The Only Girl in the World singer must have forgotten how many young fans look up to her. This prompted many fans to Tweet back with concern, but the singer ignored the comments, and went on to say, "British Vogue here I come....#ontothenextone".

The outspoken pop star recently opened up to Glamour (she's the August cover girl) about the pressure of being a role model, exclaiming: "I want to set the right example and, at the same time, live my life. I feel like pop stars can’t be rock stars anymore because they have to be role models, and it takes the fun out of it for us, because we just want to have fun with art."
