Paris Hilton, she's not nearly as air headed as she pretends to be. -u/Teuflisch

Almost all heavy metal rockers are anything but moody devil worshipers. It's always been hilarious to me that in reality, Alice Cooper is a soft-spoken Christian. -u/drygnfyre

Larry the Cable Guy isn't even a redneck. He's from Los Angeles, and the entire thing from costume to accent is a schtick. -u/redkat85

Jimmy Fallon laughs like he has a sniper pointed at him at all times set to fire when he doesn’t laugh dramatically. -u/MrBirb

Old skool here: Marilyn Monroe. She acted like a ditzy blond but behind the scenes she was hella smart and something of a literary buff (one reason she was attracted to Arthur Miller). -u/HoraceBenbow

Hilaria Baldwin is a pretty obvious one if she even counts as a celeb. -u/jaws3227

I feel like Julia Roberts is portrayed as America's Sweetheart but is reportedly a nightmare of a person. but I read that on the internet soooo. -u/dontonefingerme

Garth Brooks. Tell us where the bodies are Garth. -u/adenosine3phosph8

Gordon Ramsey…. I curse worse when I run a kitchen and it’s all an act… he’s retained like 85% of his staff for more than 15 years I’ve read… if he was really an a-hole they’d leave -u/tweezer606060

Benedict Cumberbatch. He carefully avoids having any discerning personality, and we know next to nothing about him. -u/Ok_Sheepherder_8313

Julie Andrews aka Mary Poppins. A family member worked with her very closely on a few productions. She's tough as nails, way smarter than she leads on, and has the mouth of a truck driver. -u/fulthrottlejazzhands

William Shatner is the walking poster child of insecurity. -u/MAJORMETAL84

Ariana Grande. She's just playing a characters in public I bet she's not even slightly the same person at home. -u/CaptainSebT

Drake. His whole image is one big marketing persona. You would think he stopped acting when he left Degrassi but he’s been acting his whole life. Honestly, if you look at his IG, Twitter and Facebook page, everything is about promoting his brand and there’s no ‘authentic’ version of himself in the online space. He doesn’t do interviews anymore either. -u/pretzelwins

I've read somewhere Jake Gyllenhaal puts on a fake public persona. Which is sad to me. I love that guy. -u/phillipthethird3

Adam Levine, a few years ago he had an act in Latin America's biggest music festival "Festival de Viña del Mar" in Chile, he was a massive a**hole, he asked the whole staff to not look at him in the eyes, instead made people turn around and look at the walls whenever he was walking. -u/Kriger369

Priyanka Chopra. She used to come into the hotel that I valeted at and she was always incredibly obnoxious and rude. -u/weeblesweeble

Tyra Banks has always seemed fake as f**k to me. -u/CagedandPantied

Jennifer Lawerence. Idk why but I’ve always felt that her whole “I’m quirky and awkward bc I like to eat food” was disingenuous. -u/GingerBread79

Anne Hathaway, but I guess it doesn’t count if she’s been recorded being a prick to her staff behind the scenes. In Japan, she was voted worst celebrity to work with lol. -u/TheKidfromHotaru

Kanye. He's a very disciplined performance, I can't believe he's like that in real life. -u/godarddd

50-cent, admitted that he plays a stage character during concerts, because audiences and fans want to see that particular side that matches his music. -u/TheRavingRaccoon

Millie Bobby Brown there's something off about her. -u/WolfThick

Chris Pratt. I hate to say it but since he and Anna Faris split, his new wife and his Instagram posts are just…weird. -u/Yippee614

Taylor Swift. I like to believe that the album "reputation" reflected her real self and she was just tired of the act for a while. -u/cutiegirl88
