TAYLOR SWIFT is back! The country music superstar is always so sweet and so much fun when she swings by to visit Ellen -- and today she'll give the world premiere performance of her song "The Story of Us." No one will be able to take their eyes off the screen when sexy JON HAMM stops by! He's not just good looking, he's got a great sense of humor, and he's putting it to use in the new comedy, "Bridesmaids." The last time NENE LEAKES was here, she had a lot of strong words for her "Celebrity Apprentice" co-star, Star Jones, who was happy to return the favor last week! Now NeNe is back to update Ellen on everything that's happened since -- and what we can expect in the finale! (thetvdb.com)
