(Cover) - EN Showbiz - Jay-Z believes that Rita Ora's "energy is infectious."

The music mogul signed the British singer to his label and management company Roc Nation in 2010. Rita has just landed her first UK number one with her debut track R.I.P.

Jay-Z was impressed with Rita immediately and continues to be one of her biggest fans.

"She's one of the people that, if you were in the position, you say, 'I'm gonna help her get her dream out and then we'll see what happens,' " Jay-Z told MTV News. "I think her energy is infectious, because out the gate, two #1s in London and she'll just continue to grow from there."

Rita's buoyant optimism really inspires Jay-Z.

"She was the cool girl that worked in the sneaker store in the hood and everyone knew of her. She was just in there dreamin' and she just wanted it so bad," he described. "You could just feel the excitement and the energy when she walks in the room, the room really changes. I know a lot of people say that and it gets to be clich, but when she walks into a room, her energy picks you up." (C) Cover Media
