Performance TV Round-Up: Alicia Keys, Ariana Grande & Leona Lewis...

Over the weekend, Ariana Grande and her boyfriend Nathan Sykes performed their duet at the B96 Pepsi Jingle Bash. Aren't they going through some career drama right about now? Perhaps. But at least they'll be there to console each other when Nathan's band gets dropped and while Ariana faces a lawsuit for violating copyright infringement.

Meanwhile, a packed out crowd braved the rain at Martin Place yesterday morning to watch Alicia Keys warble her way through a 3-song set on Seven's 'Sunrise' breakfast program in Australia. And last but not least, Leona Lewis visited The Jonathan Ross Show, to continue promoting the hell out of that Christmas album.
