Chris Brown Tells Rihanna to Cover Up

Chris Brown has reportedly told rumored girlfriend Rihanna not to wear such revealing outfits.

Brown is said to be worried that the Umbrella hitmaker will attract too many male admirers unless she covers up her sexy curves.

A source says, "Chris adores her, but he gets a little jealous when she is strutting her stuff.

"Her stage costumes are racy, and when she is not performing, she likes to dress to impress."

Despite Chris' jealousy, Rihanna -- who is still yet to confirm she and the 19-year-old pop hunk are dating -- is determined to continue showing off her fantastic figure.

The source added, "She is sexy and likes to dress sexy."

Earlier this week, Chris insisted he wasn't prepared to speak about his apparent romance with 20-year-old Rihanna.

The 'Forever' singer -- who has been spotted kissing the pop beauty on numerous occasions -- said, "Nobody wants to focus on what's positive, everybody just wants to know about my personal life.

"Every interview I do, it's like, 'So, how are you and such and such doing?' And I'm like, 'I don't know you, why you all in my business?' "
