10+ Pics Of Female Celebs From 20 Years Ago To Now Showing How Much They've Changed

What were you doing 20 years ago? How much have you changed in that time? These are the kind of fun questions I like to ask when I'm feeling nostalgic.

I thought it might be fun to apply the thought process to some of our favorite Hollywood actresses. Get ready to check out these 10+ pics of female celebs from 20 years ago to now, showing just how much they've changed.

Katherine Heigl.

Portraying Arlene in the lusty comedy 100 Girls was one of Katherine Heigl's first breakout roles. Sadly, not many people got to see it.

More than likely, you'll remember her as the slightly-stuck-up Alison Scott, from Judd Apatow's classic comedy Knocked Up.

Hilary Duff.

Holy heck, I'm actually old enough to remember when Agent Cody Banks hit theaters. Probably because that's where I saw the film for the first time.

Between Hilary and I, can you guess which one of us looks as gorgeous and youthful as they ever did?

Elizabeth Banks.

One of these pictures is Elizabeth Banks from 20 years ago — can you tell which is which? You can't because I couldn't; because she hasn't changed at all!

If anything, Elizabeth is aging in reverse and somehow looks younger.

Jessica Alba.

Jessica Alba had barely turned 18 when she began filming Idle Hands. To this day, it's one of my all-time favorite Halloween movies.

Jessica is still acting and is the founder of The Honest Company.

Natalie Portman.

From the very first moment I saw Natalie Portman in Leon the Professional, I knew she was destined for great things.

Since then, she's gone on to become an Oscar-winning actress, a distinguished scholar, and the founder of handsomecharliefilms.

Cameron Diaz.

If I didn't tell you that the picture on the left was from Charlie's Angels, would you have been able to tell which photo was then/now?

Aside from the fact that Cameron's hair is a little longer, these look like mirror-images.

Anne Hathaway.

I know that the hair and makeup team intentionally styled Anne's hair in a perm for The Princess Diaries. But my gosh, it's still a sight to behold.

Did you see Anne in the remake of The Witches? What did you think?

Emma Watson.

No matter how old I get, I'll always think of Emma Watson as Hermione Granger. For me, she was the diamond in the rough of the entire Harry Potter franchise.

I still haven't seen her as Meg in Little Women but it's on my list.

Megan Fox.

Megan Fox isn't a kid anymore, that much is certain. I always gravitated toward her acting and thought that she got a bit of a bad rap after the whole Transformers fiasco.

Recently, she and rapper Machine Gun Kelly took their relationship public.

Denise Richards.

Denise Richards holds a special place in my heart. Her cameo on Friends helped create what may just be the funniest Ross-moment of the entire series.

Do you remember the episode where Ross tries to kiss his cousin? It's hysterical.

Sofia Vergara.

20 years ago, Sofia Vergara was still just trying to make a name for herself. Thanks to a brief but memorable role in the Tim Allen comedy, Big Trouble, Sofia was able to set herself upon the path of superstardom.

Hayden Panettiere.

I have a little tradition to kick start the football season. I always sit down and watch Remember the Titans. It's a fantastic movie, and Hayden Panettiere is commanding in it.

Without a doubt, it's one of the best child acting performances I've ever seen.

Jamie Lee Curtis.

I just need to take a moment and says that I am beyond excited for the forthcoming Halloween Kills reboot/sequel with Jamie Lee Curtis!

I'm also a huge fan of her grey hair. She's a total silver-fox.

Christina Applegate.

I grew up on Christina Applegate. So to me, she'll always be timeless. She's another one who somehow seems to only become more and more beautiful with age.

I wish I could say the same, but sadly — I cannot.

Scarlett Johansson

I love Scarlett Johansson; she's one of my favorite actresses. I have such deep respect for her talent, her commitment to her characters, and her undeniable ability to draw an audience in.

I still can't believe that she was robbed not once, but twice this past year at the Oscars.
