Rihanna jealous of Beyonce's good looks

The Diamonds singer Rihanna - who recently confirmed she is no longer together with Chris Brown after briefly reuniting with the 23-year-old R&B star despite the fact that he is still under supervised probation for beating her in 2009 - has admitted that Beyonce, who is married to her "genius" mentor Jay-Z, makes her feel insecure.

Asked what she thought of the 31-year-old Diva singer, the 24-year-old popstar told Bravo's Andy Cohen during a Facebook Live interview last Thursday, "Gorgeous. A stab to my self esteem."

But she later admitted that despite being a huge fan of Madonna as well and wanting to collaborate with her on a song, she is quite happy being herself.

She said: "At this point I am so good with being Rihanna. I love her. Like I'm cool, I'm okay."

The 'Rude Boy' singer claimed that in 30 years time, she just wants to be happy with her figure.

She said: "I want to be skinny. I want to be fierce. I hope my t*ts are still sitting up. Nothing else will matter at that point."

Rihanna's candid comments come just days after she admitted she felt insecure after performing alongside some of the world's top supermodels in the Victoria's Secret Fashion Show in New York City and planned to hit the gym after seeing models including Miranda Kerr, Doutzen Kroes and Adriana Lima's bodies up-close.

She said: "I need to hit the gym after seeing these girls. When I sing I'm going to suck in [my stomach] and arch my back and try to remember my songs at the same time."
