Photobombs are a hilariously unpredictable part of our image obsessed lives, and even though some photobombers ruin a perfectly good pic most make that captured moment much more memorable.
Photobombing began way before the camera phone, and celebs are so used to being photographed that it's only natural for them to want to photobomb their fellow famous folks
Decades later the most underrated Beatle could still be seen carrying on the tradition of Mod photobombing by sticking it to the Bieb from behind his back...wait, that doesn't sound right?!
Of course, most photobombers aren’t famous, despite their efforts to insert themselves into as many pictures as possible, but you don't have to be famous to feel like a million bucks
