We love playing the twin game with lookalike stars from today, but what about the modern A-listers who look exactly like icons from yesteryear? From old Hollywood glamazons to current "it" stars, here are the mind-blowing side-by-sides of some of our favorite celebs and their counterparts from another era.

From their big eyes to their full cheeks, it's hard to tell the difference between a young Helen Mirren and Jennifer Lawrence.

Both in looks and personas, Sofia Vergara is Sophia Loren's modern day counterpart. Given their sultry looks, it's no surprise the two women became sexy screen sirens.

If they weren't decades apart in age, we'd be pretty sure that Lauren Bacall and Karlie Kloss, with their heart-shaped face and deep set eyes, were long lost twins.

Liv Tyler possesses the same delicately fair skin, dark hair, and green eyes that made Ava Gardner one of the biggest film stars in the '40s and '50s.

If you told us model Jourdan Dunn was the '80s singer Sade's clone, we'd believe you. Their almond-shaped eyes are almost identical.

People have often compared model Kendall Jenner to the '70s actress Ali MacGraw, and it's clear why. It's not just their long dark hair though—they give the same stare to the camera, too.

We think it's their oval faces and slender jawlines that make Brandy the spitting image of '60s actress Olga James.

A pre-mustache Tom Selleck reminds us a lot of The Vampire Diaries star Ian Somerhalder. Maybe Ian should give a 'stache a go?

Both Audrey Hepburn and Lily Collins have the acting chops to back up their beauty. The two actresses also share many of the same petite facial features.

No, you're not seeing double. Orange is the New Black star, Uzo Aduba, has the same million-watt smile that Gladys Knight was known for.

She may have played Marilyn Monroe in My Week With Marilyn, but Michelle Williams more closely resembles French film star Brigitte Bardot, if you ask us.

It's his soft eyes that make the devilishly handsome George Clooney a dead ringer for legendary actor Clark Gable.

Shalom Harlow and Olivia Wilde share the same square-shaped face and almond eyes. And lucky for both of them, this combo seems to be the key to being photogenic.

Not only are they both chart-topping singers, but Harry Styles takes after the legendary Rolling Stones singer in the looks department, too, sharing a similar nose and eyes.

Actresses Dorothy Dandridge and Maya Rudolph share the same oval-shaped face and subtle smile.

A few years his junior, Joseph Gordon-Levitt is very reminiscent of the late Heath Ledger with their thin smiles and dark, deep eyes.

The resemblance between Helen Hunt and Leelee Sobieski is remarkable. We think it's their oval face shape and serious stare.

We're not sure if French actor Vincent Cassel has the dance moves of Fred Astaire, but between their strong chin and slight grin, we'd say he's a chip off the ole block.

Friday Night Lights star, Minka Kelly, resembles actress Raquel Welch in many ways, including her wide set eyes and stunning smile.

The Queen of Pop and up-and-coming artist Sky Ferreira owe it to their short, sleek jawline for looking so similar. They have pretty similar brows, too.

Megan Fox may not share Jayne Mansfield's platinum blonde hair, but their brown eyes and full pouts make Megan nearly identical to the late film star.

It isn't just her success on the catwalk that has the fashion world buzzing that Bella Hadid is the next Carla Bruni—her high cheekbones make her a dead ringer for Bruni back in the '90s, too.

In every other way, Queen Latifah is truly unique, but when it comes to her looks, the singer and actress has a striking resemblance to novelist and folklorist Zora Neale Hurston.

The '30s film star, Hedy Lamarr, was glamorized for her fair skin and dark hair throughout her career. Almost 60 years later, Rose McGowan launched her film career with oddly reminiscent characteristics of the late actress.

Even though Cate Blanchett is slated to play Lucille Ball in the new Amazon biopic about the late actress, we're still holding out hope that Debra Messing will get to play her one day. It's not just their fiery red hair—their personalities seem similar, too.

Empire actress Taraji P. Henson bears an uncanny resemblance to '60s Motown singer, Tammi Terrell. It's like looking in a mirror, well, for Taraji P. Henson that is.

Christina Aguilera and '40s icon Ginger Rogers share more similarities than just being blonde bombshells. They also both made it in Hollywood as singers.

Sure, Mark Ruffalo and Burt Reynolds are both immensely talented and notoriously laid-back actors, but they also share the same jawline.

We know Gwen Stefani will be elated by this matchup. After all, the singer first started dying her hair platinum blonde to emulate the screen star. Their famous red pouts are just the cherry on top.

This as our official plea for Jessica Paré to play Jane Birkin on screen. One was a '70s fashion icon and the other played a '70s housewife on Mad Men, but both are essentially carbon copies of one another.

Both Cara Delevingne and Stevie Nicks exude a rocker chic energy that's undeniable, but the two also share the same round button nose.

Are we seeing double? We think it's their brown eyes that make Kate Mara looks just like The Graduate star, Katharine Ross.

Three Sharon Tate films premiered in 2019, but not one cast Sharon's present day doppelgänger (at least, according to us), Rose Byrne.

Joan Crawford was famous for her high arching brows, which she popularized in the '40s. We think that the same characteristic on Kate Winslet is what makes the two actresses look so much alike.

It's normally Amy Adams that the public confuses Isla Fisher with, but looking back a few decades we can't stop seeing the likeness between Isla and Bye Bye Birdie actress Ann Margret.

Both Joan Fontaine and Chloë Grace Moretz started acting as children, but it's their high cheekbones and sharp chins that give them even more in common.

Both Paul Newman and Ansel Elgort have worked on an impressive number of films, and both actors share the same full lips and jawline that gives them their movie star looks.

Between Sandra Dee and Carey Mulligan's pale complexions, full cheeks, and almond eyes, the two actresses could not be more alike—despite working in Hollywood decades apart from one another.

From their floppy blonde hair to their chiseled jawline, it's easy to see why Brad Pitt and Robert Redford were the heartthrobs of their respective generations.
