Kate Middleton attends 1st public engagement since cancer diagnosis [Video]

Eight months after announcing she was diagnosed with cancer, Kate, the Princess of Wales, stepped out Thursday in her first public engagement.

Kate, 42, joined her husband Prince William in Southport, England, the site of a knife attack at a local dance school in July that left three children dead and nine others injured.

Kate and William met with the fire, ambulance, air ambulance and police services at the Southport Community Centre, according to Kensington Palace.

They also met with mental health health professionals that are working to support community members after the attack, which took place at a Taylor Swift-themed event.
