This needs to be said up top: We are pretty sure Jennifer Garner is a vampire because she has. Not. Aged.

Now that that's out of the way ...

Garner played the "big time magazine editor" and totally nailed the whole "thirty, flirty and thriving" thing. Since dancing the "Thriller" straight into our hearts, Garner has starred in plenty of films like Peppermint, Dallas Buyers Club, Juno and Love, Simon. She also sweetly voiced Mama Llama for the animated kids series Llama Llama and is the most relatable mom on Instagram. She's slated to star in Yes Day on Netflix. On top of acting, the mom of three founded Once Upon a Farm, a company that creates organic baby food.

Ruffalo played Matt, Jenna's high school best friend turned love interest. Since 13 Going on 30, Ruffalo has stepped into the (very big) shoes of the Hulk (a.k.a. Bruce Banner) in the Avengers franchise, and has been nominated for three Oscars for his roles in The Kids Are All Right, Spotlight and Foxcatcher. The father of three will pull double duty playing twins in the HBO miniseries I Know This Much Is True next!

Greer plays double-crossing Lucy Wyman who is, like, so not a good friend to Jenna! Greer has been busy since 2004, having voiced characters on shows like Family Guy, Archer and American Dad as well as acting on shows like Californication, Arrested Development and Two and a Half Men. Like many of her other 13 Going on 30 costars, Greer also joined the Marvel Universe when she played Paul Rudd's character's ex-wife in Ant-Man and the Wasp.

Since the film's release in 2004, the father of three has been busy acting in franchises like Lord of the Rings and Star Wars.

He's set to appear as Alfred Pennyworth in the upcoming film, The Batman in 2021.

That's right, these two were in 13 Going on 30, can you believe? They both were part of the Six Chicks, the popular clique at school Jenna wanted so badly to be part of.

Even more amazing, the actresses are both 30, flirty and thriving themselves this year!

Both women are still acting, with Benson having starred in the popular series Pretty Little Liars and Larson going on to win an Oscar for her work in Room and play Captain Marvel in the Avengers movies.

Allen played the younger version of Garner's character, the sweet, bra-stuffing, desperate-to-be-popular teen - her first-ever acting role. And it wasn't the last time she'd play a younger version of Garner: she did it again in the 2009 movie Ghosts of Girlfriends Past. In the years since, she has continued to act both on television in shows like Revenge and Baby Daddy and in TV movies.
