10 of the worst people to work with in Hollywood (With Pictures)

5. Lady Gaga

Lady Gaga may seem like the nicest and sweetest person with her fans, but working with her can be a real chore. Just ask her former personal assistant, who sued the songstress for forcing her to do the craziest things with her. Jennifer O’Neill claims Gaga made her share the same bed with her whenever they were on the road working together; she thought it was totally inappropriate, wondering why Gaga couldn’t get her another room to sleep in. Jennifer also claims that Gaga would behave strangely and act like a maniac throughout their time together, adding that the work kept her so busy, the singer would rarely give her time off from the job.
