Kate Middleton makes her first public appearance since announcing third pregnancy

Kate Middleton stepped out for the first time since announcing she’s pregnant with her third child, debuting a tiny baby bump during a public engagement.

The Duchess announced her pregnancy in September, and was last seen in public on August 30. The palace revealed that she was suffering with hyperemesis gravidarum - a severe morning sickness which affected her previous pregnancies - meaning she has been unable to leave the house.

A palace rep confirmed that Catherine is still affected by HG, but said her condition is improving.

Kate joined husband Prince William and brother-in-law Prince Harry to host a reception at Buckingham Palace recognising mental health workers. The trio, who campaign for Heads Together, held the event on World Mental Health Day to show their dedication to the cause they all believe strongly in.
