R+B beauty Rihanna has dismissed suggestions she's feuding with pop chart rival Beyonce Knowles, insisting she has bought three copies of the IRREPLACEABLE singer's new album. The Umbrella hitmaker has been caught up in a storm of controversy, which started with reports she was making moves on Beyonce's boyfriend Jay-Z. And, of late, reports have suggested Beyonce and Rihanna have become sworn enemies as they battle for R+B supremacy on the charts. But the pretty Barbados-born star insists nothing could be further from the truth - she's a huge fan of the former Destiny's Child singer. In fact, she's so devoted to Beyonce, she has bought three copies of her so-called rival's last album B'Day - because her friends keep stealing it from her house. She tells WENN, "She's definitely not the enemy, it's not a competition. I love her, I love her so much. "I've bought that album three times - because my friends keep stealing it from me."
