Tom Cruise hasn't lost his sense of humor:

While shooting a film in the UK, he's been using a fake name at his hotel... and he's been telling guests it's his "porn name": Cage Hunt.

Here are other celebrity aliases they use when making a hotel or restaurant reservation:

Brad Pitt and Angelina Jolie: Bruce and Jasmine Pilaf
George Clooney: Arnold Schwarzenegger
Jennifer Aniston: Mrs. Smith—particularly ironic since that's the name of Angelina's character in the movie that introduced her to Brad...
Johnny Depp: Mr. Stench, Mr. Drip Noodle, and Mr. Oddpong
Justin Bieber: Chandler Bing
Kim Kardashian: Princess Jasmine
Matt Damon: Mr. President
Britney Spears: Ms. Alotta Warmheart,"
Elton John: would check in under Sir Humphrey Handbag and Bobo Latrine.
Justin Bieber: to avoid his fans he uses Chandler Bing, the name of Matthew Perry's character in the show 'Friends'.
Kate Beckinsale: Sigourney Beaver.
Lindsay Lohan: uses Bella Lovalace as her alias.
Michael Jackson: used to go by the name Dr. Doolittle when he wanted to go unnoticed.
Paris Hilton: uses her dog Tinkerbell's name to avoid fans.
Beyonce: used the alias Ingrid Jackson.
