Prince William has cheekily joked about wife Kate Middleton's hair - calling it a 'nightmare'.
The royal made the joke when he visited his charity Centrepoint's health and wellbeing centre in Soho, central London, on Thursday morning.

When the second-in-line to the throne joined a "speed mentoring" session where businesses were providing careers advice to people rebuilding their lives, he joked with a trainee hairdresser, known only by her first name Angel, that she should try styling Kate's "nightmare" hair.
Kate is famous for her gorgeous glossy signature curls, so we know what you're thinking: What nightmare hair? Kate's mane is usually coiffed to perfection.
But, it's actually known to get rather frizzy when it hits humidity.
This was particularly clear when the royal couple travelled to the Pacific Ocean island of Tuvalu back in 2012.
Thankfully, Kate's lucky enough to be able to have a hairdresser on-hand whenever she travels now.
According to the Mirror and the Daily Mail, hairstylist Amanda Cook Tucker joined Kate and Wills on their recent trip to New York, and ensured not a hair was out of place while she was Stateside.

The paper adds that Kate also regularly gets her hair dyed at the Richard Ward salon in Chelsea.
During his visit to homeless charity Centrepoint, the Duke also joined in a healthy breakfast session, which involved young people learning about nutritional food.
He then joined his wife - and the rest of the royals - for a Christmas lunch at Buckingham Palace, where, unsurprisingly, Kate's hair was perfect in a half-up do.
Wonder if he got kicked under the table...
