Throughout the Harry Potter film series, we’ve seen Emma Watson transform from a lovable child star into a burgeoning sex symbol. She’s not the first actress to do so, and she certainly won’t be the last. Here are 18 actresses who’ve gone from cute kid to gorgeous grown up. Click through to see them all.

Emma Watson

The best contemporary example of child star turned hot actress, Emma Watson has been charming audiences since she first appeared as Hermione Granger in Harry Potter and the Sorcerer’s Stone. Here’s to a long and healthy career for man’s favorite witch.

Bonnie Wright

Another Potter alum, Bonnie Wright plays the quiet, red-headed Weasley sister who ends up bagging the hero. At some point in the series she developed a serious case of “oh my god she’s hot now.”

Emma Roberts

The daughter of Eric Roberts (and the niece of Julia Roberts) Emma Roberts got her start in Hollywood at a young age, having been inspired by her father and aunt. Her debut came in 2001 with a role in the narcotics saga Blow. Nowadays she’s a gorgeous up-and-comer with a collection of notable roles under her belt.

Natalie Portman

From the moment Natalie Portman first appeared in Leon: The Professional, it was clear this young chick was going to do big things. Years later she’s one of the most bankable stars in Hollywood. Also, she’s super hot. Did we even need to mention that?

Drew Barrymore

The wide-eyed little girl from ET is today one of the most recognizable (and attractive) actresses in the world.

Jennifer Connelly

Jennifer Connelly is a big-name celebrity now, but at one point she was a little-known child actress. Then David Bowie put her in Labyrinth, and a star was born.

Scarlett Johansson

No introduction needed. Scarlett, we love you and we’re glad your child-star days yielded a successful career. Wanna go out some time?

Alyssa Milano

The sky is pretty much the limit once you appear alongside Arnold Schwarzenegger in one of the best action movies of the eighties, and Alyssa Milano certainly didn’t stop at Commando.

Daveigh Chase

Remember that freaky ghost chick from The Ring? Of course you do. You still have nightmares about her sometimes. Well, turns out she’s super hot now. Your dreams just got a whole lot less frightening and a whole lot more… well… you get the idea.

Christina Ricci

Christina Ricci was one of those children who somehow managed to be creepy and endearing at the same time. Mainly creepy, but you’ve got to admit she was a cute kid. Now she’s a hot grown-up with a successful career.

Amanda Bynes

Amanda Bynes hasn’t had the most successful grown-up career, but that doesn’t make this former child star any less of a hottie.

Alyson Hannigan

Alyson Hannigan has been in front of a camera since before she could walk, having appeared in an instructional parenting video when she was a baby. Now she’s the cute redhead we all think of when we think of cute redheads.

Katherine Heigl

Love her or hate her, it’s hard to deny that Katherine Heigl is a bona fide smokeshow. But before she landed her career-making roles in Grey’s Anatomy and Knocked Up, Heigl was a child star and model trying to break into the business just like the rest of them.

Jenny Lewis

An eighties child star known for her roles in such teen-oriented classics as The Wizard and Troop Beverly Hills, Jenny Lewis occupies her time these days fronting indie rock outfit Rilo Kiley. She also spends a lot of time being ridiculously cute.

Anna Paquin

Best known these days for canoodling with vampires on True Blood, Anna Paquin found stardom early on when she snagged an Oscar win for her role in The Piano at the age of 11.

Hayden Panettiere

Since gaining attention with a role in Remember the Titans at the age of 10, Hayden Panetierre has gone on to capture a broad fan-base, both for her acting chops and for her looks.

Eliza Dushku

Eliza Dushku, one-time Buffy star and long-time hottie, got her start early on with a role alongside Robert De Niro and future superstar Leonardo DiCaprio in This Boy’s Life.

Michelle Trachtenberg

What pre-teen boy in the 1990s didn’t have a crush on Harriet the Spy? She was such a badass. Now Michelle Trachtenberg is gracing the covers of lad mags and keeping hope alive for young men everywhere that they may someday marry their childhood hero.
