Mim-Mim, star of FremantleMedia's preschool series "Kate & Mim-Mim," made his first-ever visit to No. 11 Downing Street for a Christmas party in honor of the Starlight Children’s Foundation for children with serious and terminal illnesses.

The giant purple bunny joined singer Geri Halliwell, pop act McBusted, X-Factor star Lauren Platt, television presenters Dick and Dom and "Strictly Come Dancing" stars Pixie Lott, Jake Wood and Janette Manrara at a tea party hosted by The Rt. Hon George Osborne MP, Chancellor of the Exchequer last Wednesday.
