His grandmother was at it last week and on Monday Prince Harry couldn't resist photobombing New Zealand rugby officials at the Commonwealth Games.
Rugby sevens coach Trevor Shailer posed for the picture at the swimming event in Glasgow and could hardly contain his joy when he posted it on Facebook.
"Photo of the day....A Royal photo bomb by Prince Harry with Titch (Sir Gordon) and Gary Hermansson at the Swimming venue tonight," Shailer wrote. "Thanks to Bev Hari for taking the pic...fun times supporting our athletes at the Glasgow Commonwealth Games!!"
The 29-year-old prince's effort comes a week after the Queen photobombed an Australian hockey player's selfie last week.
