No awards ceremony these days is complete without a celebrity photobomb. This year's Oscars saw two classics. First, Benedict Cumberbatch loomed comically over U2 as they were having their photo taken, and then Jared Leto danced around behind Anne Hathaway as she was posing at the Vanity Fair party.
IBTimesUK pays tribute to the masters of the celebrity photobomb. Cumberbatch, Leto, Emma Thompson, Kevin Spacey, Tyler the Creator ... heroes one and all.
