It's tough to make a living in Hollywood, and it only gets tougher with age.
That goes doubly for women in the film industry, who are often forced to conceal their age in order to avoid being automatically ruled out for certain roles.
In 2012, Jessica Chastain was caught lying about her age. Last year, Rebel Wilson admitted to doing the same.
Both women are now at points in their career where they can confess to misleading a few casting directors and still find work.
However, they might have never gotten the chance to establish themselves if they hadn't fibbed a bit on their resumes.
So when we present the following list of celebs who have been accused of lying about their age, we do it not to shame them, but, well ... simply because it's fun to guess how old they really are.
Jump into the gallery below for a list of stars who may have turned 29 a half dozen times. Just don't judge them to harshly.
After all, sometimes you have to play with the truth in order to get to the top - and just about every politician on Earth is guilty of far worse fabrications than these.
Blake Lively - 28
Blake Lively says she's 28 years old. Rumors that she's lying about her age have haunted her since her Gossip Girl days.
Margot Robbie - 25
Margot Robbie claims to be 25, but many fans have pointed out that she looks a bit older. Hey, that Australian sun will do a number on your skin.
Lindsay Lohan - 29
LiLo certainly looks older than her 29 years. The sad part is, in this case, we don't think she's lying about her age as much as we think her lifestyle has added at least 11 years to it in terms of mileage.
Adele - 27
Maybe it's her old school style, but some folks think Adele's latest album should be titled 35-ish.
Coco - 36
Coco says she's 36, and frankly, we believe her. Hell, there are far more unbelievable things about her body than her age.
Bella Thorne - 18
Obviously, Bella is gorgeous, but does she look 18? We suspect her parents might've misled some casting directors to give Bella a leg up when she was a child star.
Lady Gaga - 29
Many believe the Mother Monster is misleading fans about her age. We believe her, though. After all, it wasn't that long ago that we saw her hatch from an egg at the VMAs, so she can't be that old!
Lorde - 19
Lorde was 17 when she scored her first international hit. Her looks and talent make it hard to believe she's still in her teens.
Kate Upton - 23
Kate Upton is 23? That can't be, right?
Angelina Jolie - 40
Okay, so Angelina can't be SECRETLY 40, since she claims to be 40, but lots of folks in Hollywood think the actress and activist is actually several years older than she claims to be.
Kate Winslet - 40
Kate Winslet looks 40. It's the fact that she's looked 40 for several years that's led to rumors that she lies about her age.
Britney Spears - 34
If Britney is lying about her age, she started when she was very young. But hey, those Disney folks are a sneaky lot.
Mariah Carey - 45 (or 46)
Stories differ as to when exactly Mariah was born. She's also been known to pass off decade-old photos as present-day selfies. We wouldn't put it past to her to shave a few years off her age.
Tara Reid - 40
Tara Reid looks kinda rough for a 40-year-old. Of course, that was true when she was 25, too.
Kylie Jenner - 18
Okay, so Kylie Jenner is obviously 18. Almost her entire life has been that of a celebrity whose every moment has been for public consumption. So she's not lying ... she's just growing up faster than any 18-year-old the world has ever known.
