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.

3) Katy Perry and her then-husband Russell Brand were photobomed by Justin Bieber at the 2011 Video Music Awards. The couple sat directly in front of the Beauty and a Beat singer at the awards ceremony. When the husband and wife posed for a picture, Bieber stuck his head in between theirs and made a gasping face for the camera.

The 2011 VMAs was also one of the last public appearances Bieber made with his girlfriend at the time Selena Gomez. They split in late 2012 but are reporting in an on-again, off-again relationship.

4) Demi Lovato was photographed sitting next to her friend Nick Jonas at the 2013 Teen Choice Awards on Aug. 11 but her ex-boyfriend, Joe Jonas, sat behind them and decided to photobomb their picture. As Lovato and Nick smiled for the camera, Joe made a silly face in the background. The singer then uploaded the comical shot on Instagram with the caption, "Just like old times. #TCA."

Joe and Lovato briefly dated in 2010.

5) It is not clear who is really photobombing who in the below image, but Johnny Depp and Tim Burton were photographed this way at a 2010 photo session to promote the movie Alice in Wonderland in Tokyo. The actor and director have worked together on a number of films, including Edward Scissorhands, Corpse Bride, Sweeney Todd: The Demon Barber of Fleet Street and Charlie and the Chocolate Factory.

6) Clarkson was "photobombed" by Bill Clinton when she performed My Country Tis of Thee at President Obama's second inauguration on Jan. 21. The former president stuck his head out from his seat and smiled for cameras during Clarkson's performance, and paparazzi snapped photos of Clinton peering out from behind Clarkson. Three weeks later Clarkson photobombed Ellen DeGeneres and Portia de Rossi at the 2013 Grammys on Feb. 10. DeGeneres and de Rossi smiled for the cameras as they sat front row at the awards ceremony and were unaware that Clarkson was also in the picture sticking her head out into the aisle and pointing her finger toward the happy couple.

Earlier in the day, during President Barack Obama's inaugural speech, cameras caught Sasha delivering a giant yawn before clapping as her father concluded his speech. 

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.
