Despite reports in British media that the pregnant Kate Middleton, Duchess of Cambridge, is recovering from nearly a month of extreme morning sickness, she has been forced to cancel yet another royal engagement.
"The Duchess of Cambridge was unable to attend today's The Art Room engagement as she continues to suffer from hyperemesis gravidarum," Clarence House, the official residence of her father-in-law the Prince of Wales and his family, tweeted Wednesday.
The Art Room is a UK charity providing in-school art therapy for children with emotional and behavioral difficulties.
Middleton, 32, sent a message of support for a new Art Room opening as part of the Clore Duffield Foundation's 50th anniversary, writing on the Prince of Wales' official site, "I am truly sorry that I cannot be with you all today as you celebrate this milestone. As Patron of The Art Room I feel great pride to see the work that the charity is doing."
On Sept. 8, the Duchess' illness prevented her attending the opening of the China Centre at Oxford University. Two days later, she missed the opening ceremony of the Invictus Games, an international sporting event for wounded, injured and sick servicemen and women, which her brother-in-law Prince Harry supports.
On Sept. 18, she canceled her first solo official visit overseas to Malta for that nation's 50th-anniversary commemoration of its independence; her husband, Prince William, went in her stead.
Middleton and William, also 32, already are parents to the year-old Prince George.
