"The Sisterhood of the Traveling Pants" is an iconic story of friendship.

It's been 15 years since the first movie had four best friends — played by Alexis Bledel, Blake Lively, America Ferrera, and Amber Tamblyn — find a pair of jeans that fit them all. On August 6, 2008, the foursome reunited for more adventures in the sequel, "The Sisterhood of the Traveling Pants 2."

In April 2018, it was reported that a third movie was in the works. Bledel even said on "The Tonight Show Starring Jimmy Fallon" that the girls had "pitched" a concept for another movie.

While there have been no recent updates on the possible third movie, the four main girls have all gone on to star in countless other projects.

Here's a look at what the casts of both movies have been up to.

The movie was Blake Lively's first major movie role. She played Bridget Vreeland, also known as Bree, who traveled to Mexico for a soccer camp.

At soccer camp, Bree gets involved in a summer fling with one of her coaches and also opens up to her friends about her mother's mental health.

In the second movie, she goes on an archaeological dig in Turkey before traveling to Alabama to visit her grandmother, where she learns more about her own mother.

Today, Lively is best known for her starring role on "Gossip Girl," which has earned her two Teen Choice Awards.

Lively's other film credits include "A Simple Favor," "Accepted," "The Age of Adaline," and "The Shallows." A fashion icon, she'll next appear in "The Husband's Secret."

She married Ryan Reynolds in 2012, and they have three children.

One of America Ferrera's earliest roles was playing Carmen Lowell, who spends a portion of her summer with her dad and his new family in South Carolina.

Ferrera is caught by surprise upon meeting her dad's new family. After they ignore her feelings, she escapes back to Maryland. Eventually, she makes up with her dad and attends his wedding at the end of the first movie.

In the sequel, Carmen attends an actor's workshop in Vermont and earns the lead role in a play.

Ferrera went on to star in "Ugly Betty," becoming the first Latina to win a leading actress Emmy.

Ferrera's other projects include the "How to Train Your Dragon" movies and "César Chávez." Ferrera also starred and executive produced the comedy "Superstore," which she left after five seasons.

Ferrera is also politically active, advocating for immigrant rights and women's equality. She is a founding member of the Time's Up movement and legal defense fund, which seeks to end workplace sexual harassment and assault.

She married Ryan Piers Williams in 2011 and they have a son and daughter together.

Amber Tamblyn was Tabitha Tomko-Rollins, better known as Tibby, who stayed home in Bethesda, Maryland, for the summer.

In the first film, Tibby worked at a discount department store and was filming her own movie. She met a young girl named Bailey who had leukemia, and the two grew close before Bailey died.

Tibby took screenwriting classes at New York University and worked in a video store in the sequel. She also went through a pregnancy scare with her boyfriend, Brian.

Tamblyn published her first novel in 2018 and is a staunch supporter of the Time's Up movement.

Before starring in the "Sisterhood" movies, she was known for "Joan of Arcadia." She later appeared on "House" and "Two and a Half Men" and starred in "127 Hours."
