Britain's Duke and Duchess of Sussex, Prince Harry and his wife Meghan, attend a gala concert in support of charities for military veterans who face mental health challenges, in London

Nick Kent - the executive producer for the documentary 'Queen of the World' - has hailed the Duke and Duchess of Sussex, describing them as a "dream team".

The British royals tied the knot at St George's Chapel at Windsor Castle in May and Kent has hailed them as the perfect couple.

He shared: "She's a professional in front of the camera. He and Meghan are a dream team."

In the documentary, the former 'Suits' actress is reunited with her wedding dress, which features a piece of the dress she wore on her first date with the Duke.

Nick said: "When she saw the dress, she was really excited to see it and spend time looking at it. The first thing she does is she looks for that little piece of blue that she secretly had sewn into the dress."

The producer explained that the Duchess behaved in a very natural way despite the presence of the cameras.

He told 'Entertainment Tonight': "The fact that was the first thing she said and nobody knew shows how relaxed she was in front of the camera and how for her, it was a genuinely enjoyable moment. She really cherished it."

And Nick feels the Duchess is already leaving a mark on the British royals.

He explained: "A powerful example of that is the piece of blue fabric in the dress. That was a very private gesture that she made, to have that piece of fabric sewn in, nobody knew about that. The fact that she was happy to share that, you know, it's quite an intimate insight.

"The other thing, is that it's a mistake to think that the monarchy stays the same. In a sense, reinventing how you fulfil your duties as a member of the royal family is something that's not a new thing. So in a funny way, she's kind of following in the tradition of Queen herself and Princess Diana."
