Duchess of Cambridge to attend first public event since pregnancy revealed

The Duchess of Cambridge is set to attend her first public engagement since her pregnancy was announced this month, presenting prizes at a sports awards show Sunday evening in London.

A spokesman for St James's Palace, the official household of the Duke and Duchess of Cambridge, said Catherine would attend the BBC's Sports Personality of the Year Awards "in response to a long-standing invitation."

In a statement, the spokesman said: "Her Royal Highness will present the Lifetime Achievement and the main Sports Personality of the Year Awards" at the event at London's ExCeL center.

The duchess was last seen December 6 alongside her husband, Prince William, leaving the hospital where she had undergone several days of treatment for acute morning sickness.

Her stay at the King Edward VII Hospital was overshadowed by the apparent suicide of Jacintha Saldanha, a nurse who took a prank phone call from Australian DJs. The pair made the hoax call to the hospital, pretending to be Queen Elizabeth II and Prince Charles in an effort to find out details of Catherine's condition.

Catherine's illness had led the couple to announce her pregnancy earlier than the usual 12-week mark; the royal couple have not announced when their baby is due.

Health concerns have forced Catherine to pull out of several events in recent weeks, including the UK premiere of "The Hobbit" in London this week; Prince William attended the event alone.
