(CNN)The UK might still be coming to terms with the surprising news that Prince Harry and Meghan, Duchess of Sussex, are stepping down as senior royals, but there is still one cause to celebrate -- the Duchess of Cambridge's birthday.
Duchess of Cambridge gets royal birthday best wishes amid turmoil over Harry and Meghan's announcement
Catherine, wife of Prince William and mother to the third, fourth and fifth in line to the throne, turned 38 on Thursday.
The occasion was marked by several royal messages on social media.
Clarence House, the official residence of Prince Charles and the Duchess of Cornwall, tweeted four photographs featuring Catherine -- including one with Camilla and two with Charles.
The message contained a balloon emoji and wished the royal "a very Happy Birthday."
Congratulations were also sent by the royal family's official Twitter account, accompanied by three images of Catherine with the Queen and a link to a page about the work the duchess does.
"Wishing The Duchess of Cambridge a very Happy Birthday!," it read.
Thanking the public for their "lovely messages," Kensington Palace released a previously unseen image of the duchess, who is smiling and sitting against a sunny backdrop.
Dressed in jeans, a blue blouse and a brown sweater and sat on a wooden fence, the duchess is photographed by Matt Porteus.
