Who do you believe is the better DIVA?

Beyonce and Rihanna both have been recording since they were teenagers and both became major worldwide popstars on the strength of R&B and funk.it would seem that both singers have had a very good 2011, but upon closer inspection, it’s clear that the two stars are at very different places in their career: While relative newcomer Rihanna, 23,  is still in the process of establishing herself as a superstar with an abundance of singles in a bid for total radio domination, record industry veteran Beyoncé, 30, is using what she has worked towards and accumulated over the past decade to pursue a more personal vision with her most recent material.  

In my opinion, I feel as though Rihanna is the better singer. Rihanna’s incredible success at pop radio, outstanding digital track sales and overwhelming popularity on YouTube isn’t simply a matter of having her finger on the pulse of popular culture. It's partly the result of unflagging momentum – there has been hardly any time since Rihanna broke big with "Umbrella" in 2007 when she has not had a hit on the radio, either as a solo act or featured artist. People want new music and Rihanna is constantly working on new material that seems to be a hit.
