2015 has shown that celebrities are often pranksters. On April fools day Rihanna showed up at Jimmy Kimmel’s home with her friends at 1 am. They woke the presenter with confetti, disco lights and a private show of her last single “Bitch Better have my money”. Liam Hemsworth received a prank from Woody Harrelson on ‘The Hunger Games’ set. Harrelson convinced the make-up artist to tell Liam that she had had an accident and asked Liam to pick her up at a non-existent hospital. Daniel Radcliffe and James McAvoy had fun on the Frankenstein set by drawing a penis on one of props of the famous monster. And George Clooney admitted that he will trick Brad Pitt in 2016, and he could face jail for it, but he said that he is not worried because his wife is a lawyer.
