Some cousins only get to see each other at family reunions and weddings. But Jess and Janelle Martinez get to spend much more time together. Why? 'Cause they're bandmates in pop duo Prima J! Jess and Janelle first burst onto the scene last year when their debut song "Rockstar" was featured in Bratz: The Movie. But it was their cover of Alicia Keys' "No One" (remade in Spanish as "Nadie") that really caught people's attention. With their debut album on the Billboard Charts and an opening slot on Danity Kane's tour this month, one thing's for sure -- Jess and Jane aren't "No One" anymore!
