Taking a photo is not an easy as it used to be when you have others inviting themselves in the shot.

1) When Kate Middleton married Prince William on April 29, 2011, their central London wedding was televised around the world. Following the ceremony they marked their first appearance as a married couple by kissing on the balcony at Buckingham Palace. Photographers captured the romantic shot but also in the image was one of Middleton's bridemaids Grace van Cutsem, according to Reuters. The young girl did not look happy in the photo.

Middleton gave birth to the couple's first child, His Royal Highness Prince George Alexander Louis of Cambridge, on July 22.

2) On the set of Grey's Anatomy, where the cast was filming season 10 of the ABC series, eager fans were excited to take a picture with Jackson Avery actor Jessie Williams. However, his co-star Ellen Pompeo, who plays Meredith Grey, wanted in on the action. She jumped in the background of the photo while holding up her arm and sticking out her tongue. Williams uploaded the respective photo on Instagram with a caption poking fun at the photobomb.

"Ya know, i try to be a gentleman, even when fans from France & the Netherlands storm our location & penetrate our security. Its all worth it when the homie@ellenpompeo swoops in for the professional grade," he wrote.

8) Will Smith and his son, Jaden Smith, were photobombed in April by TNT correspondent Craig Sager in the midst of a Miami Heat basketball game. The father and son watched Heat play the Chicago Bulls courtside and when the camera zoomed in on them during an intermission, Sager made he was in the spotlight as well. The sports announcer maneuvered himself into position at the live game to make sure that he was in the Smith family photo.
