She stole our hearts as Lorelai Gilmore on "The Gilmore Girls," today LAUREN GRAHAM is here! She'll talk about her amazing NBC show, "Parenthood" -- she and the rest of the all-star cast have been making us laugh and cry for three fantastic seasons. The always adorable Lauren is one of Ellen's favorite people to talk to!

Then, BARRY DELEY had no idea he would win the Grand Prize when he entered the Children's Hospital Dream House Raffle.

They're here to tell their incredible story to Ellen.

Plus, Hip-Hop violinist JOSH VIETTI is here to show off his ridiculous skills on a violin that will leave your jaw on the floor.
