Princess Kate and Prince William have a "wicked sense of humour" according to Mike Tindall's close friend, James Haskell.
Mike Tindall, 46, was joined by his former England rugby team-mate on Good Morning Britain to discuss the Prince and Princess of Wales for their podcast The Good, the Bad & the Rugby.
Prince William is the cousin of Mikes's Wife, Zara, and has a good relationship with the pair.
Royal fans were delighted when the Prince and Princess of Wales appeared on the podcast last September.

In addition, the Princess Royal joined the mini-family reunion.
Speaking today about William and Kate, James said: "That podcast was brilliant because we see them at their best, obviously they have a wicked sense of humour, in this country in particularly we obviously put people on a pedestal, but they are a regular family, an incredible family they do a lot for this country but a regular family."
The podcast episode, recorded at Winsor Castle, revealed that Kate and William have never finished a game of tennis between them because it becomes a 'mental challenge', according to the Princess.
The royals were invited onto the episode as patrons of the WRU, RFU, and SRU, which was recorded during the 2023 Rugby World Cup.

Co-host James Haskell questioned the Royals on their competitive attitude towards each other.
He said: "Mike has made out both of you are super, super competitive, a bit like Monica from Friends, and if you guys play table tennis it will go on for hours and hours, and be like, double or quits."
Kate denied the claims, she said: "I'm really not that competitive, I don't know where this has come from."
She then confessed that she and William had never managed to finish a game of tennis, as "it becomes a mental challenge between the two of us."

Princess Anne revealed that William and Kate's three children Prince George, 10, Princess Charlotte, eight, and Prince Louis, five, are showing "just a little bit" signs of competitiveness.
Kate added: "What's interesting is that they all obviously [have] very different temperaments."
"As they're growing and trying out different sports - they're obviously still really young - it's going to be interesting to see how that grows and develops."
Mike also discussed Prince William and Kate in his new book The Good, the Bad & the Rugby – unleashed.
He said: "I think the podcast humanised them a little bit, and I kind of wish they'd let us put the uncut version out, because it would have blown the public away."
