New year, new ‘do! Kate Middleton stole the spotlight from Princes William and Harry when the Royal showed off a bouncy new hairstyle during her engagement at the Institute of Contemporary Arts in London on Tuesday.

The Duke and Duchess of Cambridge and Prince Harry were in attendance to promote the latest phase of their Heads Together initiative, where the trio outlined the next stages of their mental health programme, The Daily Mail reports.

“Mental health matters to each and every one of us. It matters just as much as our physical health,” Prince William told attendees. “The crews I have worked with, whether RAF Search and Rescue or Air Ambulance, must take their mental health as seriously as they do their physical health or else they would not cope – and, actually, that is true for everybody at some time or another in their life… There are times when, whoever we are, it is hard to cope with challenges – and when that happens being open and honest and asking for help is life-changing.”

The Duke continued, ‘Talking to someone else is a positive and confident step to take – but for too long it has been a case of ‘Keep Quiet and Carry On.'”

Middleton followed her Prince with a speech of her own, touching upon her meetings with sufferers of mental illness. “William, Harry and I have been very privileged to witness, in the course of our work, countless examples of simple conversations that have changed lives, which were the first step on a path to recovery,” she said. “Just last week at the Anna Freud Centre, I heard from one mother how talking to a support worker was – in her words – ‘like medicine.’ Simply by having someone there to have a conversation with helped her immensely.”

Prince Harry also offered his words of advice, saying, “The truth is we can all help each other. You don’t need any qualifications to help your mate out, simply to listen to what they have to say.”

The rich tone of Middleton’s shiny locks looked beautiful against the navy colour of her floral printed, long-sleeved dress by her go-to designer – the Canadian-born Erdem Moralioglu. The Duchess, who recently turned 35-years-old, paired the chic number with a burgundy suede clutch that matched the colour of Prince William’s tie.
