Rihanna Not Dating Andrew Bynum

According to MTV News, singer Rihanna, 21, is not dating Los Angeles Lakers center Andrew Bynum. Bynum recently denied any rumors that he is seeing the singer.

Rihanna was also rumored to have been dating actor Wilmer Valderrama after her reconciliation with fellow singer Chris Brown, 19, after he was arrested for allegedly assaulting her in February.

In March, Rihanna was rumored to have been dating actor and reality star Frankie Delgado. Delgado said of the supposed relationship, "She's been out, hanging out, I guess. It's Hollywood, people talk a lot. . . . She's good."

According to new reports, Rihanna will make an appearance at a concert in Dubai on May 28. Mary Rachelle Cherpak, a spokeswoman for Alba Hotchkiss of the Dubai Department of Tourism, said the concert would be "a concert for 25,000 audience members. This is another example of how Dubai tourism is attracting the best of the best and is one of the world's hottest destinations. . . . She chooses to do that in Dubai, which I think is a great credit to the destination that it has support of these top artists."
