Jessica Simpson, 8-Year-Old Dancer Bianca Busa

She's a pop star, a fashion icon and totally "irresistible!" It could only be JESSICA SIMPSON. She's here to catch up with Ellen on her life, and to give us all the fabulous details on her clothing line.

Then, Ellen welcomes the immensely talented and adorable BIANCA BUSA. Bianca is an 8-year-old dancer who has been dancing since the age of 2. She'll be performing a hip hop dance routine to Kendrick Lamar's "Humble." Put on your dancing shoes, because this is going to be a blast!

Monday is fun day, today on Ellen!
