The Grammys are this weekend an Ellen knows how to get the party started -- by welcoming one of the most popular musicians in the world, the Grammy-winning RICKY MARTIN! He'll treat everyone to a performance of a song from his brand new album, "Musica+Alma+Sexo," and he might even surprise the audience with one of his biggest classic hits! One of the biggest stars around is stopping by -- SAMUEL L. JACKSON! His movies have made more than any other actor's, but nothing goes to his head -- except his many cool hats! He's always up for a fun time with Ellen. Valentine's Day is coming fast, and if you don't have the perfect card picked out -- you're in luck! Ellen is sending her writer, Amy, to the card aisle to help people find the perfect way to say "I Love You!"
