When Australian women's hockey player players snapped a quick selfie after defeating Malaysia in the Commonwealth Games, they timed it just right so they could have quite the epic "photobomber:" an unusually wide-grinning Queen Elizabeth.
Despite the fact that most celebrities dislike having their photo taken by paparazzi and star-struck tourists, many of them enjoy intruding upon the photos of others. Though this one was planned (and made even better by the queen playing along), usually photobombs are a spontaneous, hilarious call for attention by someone who happens to be in the right place at the right time, and they're always great for a laugh. Here's some of the most glorious, even infamous, celebrity photobombs in recent history.
Which celebrity would you want to photobomb your selfie? Let us know in the comments below.
Correction: An earlier version of this post stated that the hockey players did not know the queen was in the background before taking the photo. This has been corrected.
