Beyonce Knowles was the special guest at the Macy’s Glamorama 2006, a star-packed fashion show last week in Chicago. She and sister Solange helped show off their mother Tina Knowles’ Deréon fashion line (named after Beyonce’s maternal grandmother, Agnéz Deréon). Other celebs at the event included former Destiny’s Child member Michelle Williams, Lauren Holly, Philip Bloch, DJ Cassidy, and Tommy the Clown.
