2. Adam Levine

The singer of Maroon 5 once called a fan ugly and refused to sign an autograph for them. If that’s not bad enough, in an interview with Cosmopolitan, Adam Levine also expressed his opinions on cheating, making excuses for why men do it. He also admitted to cheating himself and didn’t seem to upset about his actions. There have also been several occasions where he has been a dick on stage towards fans. To be honest, Levine has always acted like a bit of a tool, so it’s no surprise to find out he is one of the rudest celebrities out there. 

3. Catherine Zeta-Jones

You wouldn’t pick Catherine Zeta-Jones as someone with a bad attitude, but it appears that’s exactly what she has. The most famous story about her happened way back in 1998, so she might be much nicer now. An eight-year-old girl was attending a special screening of The Mask of Zorro. She went up to Zeta-Jones and asked her for some advice on acting, as that is the career path she wanted to follow. What wisdom did Zeta-Jones deal out? “You’re pretty enough, I suppose.” Ouch. Bit harsh to be telling an eight-year-old that. 

4. Tobey Maguire

While it is well known Tobey Maguire isn’t a fan of the paparazzi, he has also behaved questionably with others. One of the biggest incidents he was involved in occurred back in 2014 during a high-stakes poker game hosted by Molly Bloom. Maguire often took part in these games with other celebs, such as Leonardo DiCaprio and Ben Affleck. On one occasion, Spider-man showed his true colors when he offered Bloom a $1,000 poker chip if she barked like a seal. Maguire purposely embarrassed Bloom in front of other big-name celebs. It was soon revealed this was part of a plot to take control of the poker game, and that’s exactly what he did, sending Bloom out of business.
