OTRC: Kate Middleton released from the hospital after being treated for acute morning sickness

Kate Middleton, aka Catherine, Duchess of Cambridge, was released from King Edward VII Hospital in London on Thursday, December 6, after being treated for acute morning sickness related to her pregnancy.

The 30-year-old was spotted leaving the hospital holding a bouquet of yellow roses with husband Prince William, known as the Duke of Cambridge, by her side. The royal couple stepped into a waiting car shortly after exiting the hospital.

Kate is expected to head to Kensington Palace in London for a period of rest, according to The Associated Press. Her pregnancy and ailment, which is technically referred to as Hyperemesis Gravidarum, was revealed on Monday, December 3.

William was at the hospital visiting his wife every day. A palace source told ABC News that she is not yet 12 weeks along that given her hospitalization, she and her husband had made the "difficult decision to be fully open about the pregnancy from this stage."

Her stay at the hospital was complicated by a breach of her privacy when two Australian disc jockeys called up the hospital pretending to be Queen Elizabeth II and Prince Charles. The two deejays persuaded Kate's nurse to answer questions about the Duchess' condition.

The radio personalities, Mel Greig and Michael Christian, later apologized for the hoax, according to The Associated Press. They noted that they were surprised that the gag worked.

Kate's last public appearance took place several days ago, on November 30, when she spoke to students at St Andrew's School in Pangbourne -- her alma mater. During her visit, she also played some field hockey.
