Get ready, ladies! MARIO LOPEZ is here today! That's right, the gorgeous guy will be visiting Ellen before he hosts "Miss America" on Saturday. Last time he was here, Ellen finally got him to take off his shirt. Think she can do it again? She just might. Then, last week while the storms were pounding Southern California, a dog got trapped in the raging L.A. River. Firefighters tried for an hour to rescue him before calling in a helicopter for a dramatic rescue, broadcast live on TV. Today, firefighters JOE ST. GEORGE, SCOTT BOWMAN and DAN CHILD will tell Ellen everything that happened. Also, CORINNE BAILEY RAE'S first album was nominated for a Grammy, so her second one is bound to be great! Today she'll perform "I'd Do It Again."
