Prince Harry photobombed a picture of three New Zealand rugby coaches at the Commonwealth Games on July 28.

The 29-year-old royal is seen giving a cheeky thumbs-up and cheesy grin in the background of the snap as Sir Gordon Tietjens, Trevor Shailer and Gary Hermansson pose for the photo while they watch the 800m women's swimming freestyle in Glasgow.

Trevor was so impressed with the photograph that he quickly made it his Facebook profile picture with the caption: "Photo of the day.... A Royal photo bomb by Prince Harry with Titch (Sir Gordon) and Gary Hermansson at the Swimming venue tonight. Thanks to Bev Hari for taking the pic...fun times supporting our athletes at the Glasgow Commonwealth Games!"

Harry's funny photobomb comes just four days after his grandmother Queen Elizabeth, 88, found herself in the background of Australian hockey player Jade Taylor and her teammate Brooke Peris' self-taken snap.

The picture - which Jade, 29, posted on her Twitter account - shows the girls smiling at the camera while the Queen, dressed head to toe in mint green, can be seen grinning at the pair in the background of the shot.

She captioned the image: "Ahhh The Queen photo-bombed our selfie!! #royalty #sheevensmiled #amazing #Glasgow2014 @Hockeyroos @AusComGames(sic)".

Meanwhile, the Commonwealth Games kicked off in Scotland last Wednesday - July 23 - after the queen officially opened the event at the Celtic Park stadium.
