Lewis implicated in Rihanna attack

Leona Lewis has been forced to issue a statement after becoming implicated in the recent Chris Brown and Rihanna scandal.

Lewis reportedly caused the 'Umbrella' singer to fly into a rage after Brown was seen chatting to her.

"At one point, Rihanna caught Chris flirting with Leona," the source told Star magazine.

"They were carrying on and laughing, and Rihanna saw Chris with his hand on the small of Leona's back. It may have been innocent, but that set Rihanna off."

However, a spokesperson for Lewis told Holy Moly: "Leona was at the pre-Grammy party with her family and boyfriend and had nothing whatsoever to do with any argument that may have ensued between Chris and Rihanna. Any allegations that the pair had flirted are completely false."

Another friend denied the reports, telling Metro: "I can't imagine this has anything to do with Leona. Leona's not like that. She wouldn't flirt and is happy in her own relationship."

Chris Brown is reported to have allegedly assaulted Rihanna, leaving the singer with "horrific" injuries.
