Duchess of Cambridge returns to public eye after pregnancy announcement
The Duchess of Cambridge was seen in public for the first time since the announcement of her third pregnancy on Tuesday.
Catherine has been keeping a low-profile in recent weeks as she battles symptoms of Hyperemesis Gravidarum.
The mother-of-two joined husband Prince William and brother-in-law Prince Harry at a mental health event at Buckingham Palace.
The Duchess looked radiant in a blue Temperley outfit as she mingled with leading figures from mental health.
