Britain's Duchess Catherine is giving Prince Harry cooking lessons.
The duchess has a close bond with her brother-in-law and with her husband Prince William away a lot with his work as an RAF search-and-rescue pilot, she has been using her free time to give Harry some domestic tips.
A source said: ''Kate is a whizz in the kitchen while Harry's skills are rather lacking. So Kate has been teaching Harry to cook rather than use the microwave.
''Aside from the relationship they have a very brotherly, sisterly relationship and Harry has been a great support to Kate, who is still fairly new to the royal family.''
However, Harry - who caused a stir earlier this week when naked pictures of him partying in Las Vegas were published online - ought to be careful not to over-indulge in Catherine's food as the pair have jokingly nicknamed William 'Burger King' after he gained a few pounds recently.
The source added to Grazia magazine: ''It's always a laugh when Kate and Harry are together.
''William loves that his wife and brother are such good pals and he jokingly calls Harry Kate's 'lady in waiting' because he's always there by her side. What he doesn't enjoy is how much they like to wind him up.
''There's always a lot of laughter when the three are together but it's normally aimed at Wills, poor chap, but he takes it well and knows it's all a bit of banter.''
