Kate Middleton RELEASED from Hospital -- I'm Off to My Palace!

Kate Middleton has finally been discharged from the hospital ... after several days of treatment for "acute morning sickness" ... and now the Duchess says she's headed back to her palace to rest.

Kate was all smiles on her way out of the King Edward VII Hospital in Central London ... clutching some flowers ... and getting some assistance from her hubby Prince William.

Afterward, Kate's team of Royal statement writers released the following royal statement, "The Duchess of Cambridge has been discharged from the King Edward VII Hospital and will now head to Kensington Palace for a period of rest."

“Their Royal Highnesses would like to thank the staff at the hospital for the care and treatment the Duchess has received.”

God save the fetus.
