Rihanna sure knows a good thing when she sees it. After sporting a revealing low-back black gown at the Grammys, the "Live Your Life" singer gave photographers the cold should once again at the Stella McCartney fashion week presentation in London on Saturday.

The sultry singer hit the step-and-repeat wearing a teal satin gown that surely made more than a few onlookers whisper, "How low can she go?"

Although her red carpet looks have been perfect tens as of late, fans are less than pleased with news that she may be hitting the studio with ex-boyfriend Chris Brown. Brown notoriously attacked Rihanna in 2009, but the pair will reportedly be reunited on a remix of the 23-year-old's hit, "Birthday Cake."

Brown also attended Rihanna's birthday party Monday night, at which he reportedly asked fellow party-goers to sign confidentiality agreements regarding his presence at the fete.
