In the 1980s, the "Brat Pack" -- a take on the 1960s Rat Pack that included stars Frank Sinatra and Sammy Davis Jr. -- was the crowd everyone wanted to travel in.
Having appeared in movies such as "St. Elmo's Fire" and "The Breakfast Club," the group of young actors -- from Demi Moore and Rob Lowe to Ally Sheedy, Judd Nelson and others -- enjoyed fast fame, loads of money, sex and of course drugs and alcohol.
Many, but not all, eventually suffered a nosedive from the spotlight and found themselves in rehab.
On Tuesday, a publicist for Moore, considered one of the most successful of the Brat Packers, reported that the actress was seeking treatment for "stress and exhaustion."
According to People magazine, it was not Moore's first time in treatment. In the 1980s, she went to rehab for drug and alcohol abuse.
Here is a look at Moore and the rest of the gang who starred alongside her in 1985's "St. Elmo's Fire," a movie about a group of recent college graduates struggling with adulthood, and how they ended up where they are today.
|Demi Moore as Jules|
She starred in "St. Elmo's Fire" and "About Last Night" in the 1980s and was a regular on the soap opera "General Hospital." She married Freddy Moore and then Bruce Willis, with whom she had three daughters. She famously appeared on the cover of Vanity Fair magazine nude while seven months' pregnant. Moore is well known for her role in "Ghost," which featured Patrick Swayze and Whoopi Goldberg. She also starred in "A Few Good Men," "Indecent Proposal" and "Charlie's Angels." She married Ashton Kutcher in 2005, but they are now in the middle of a divorce. She was tapped to play feminist Gloria Steinem in a biopic, but has pulled out.
|Emilio Estevez as Kirby|
Estevez starred in "St. Elmo's Fire" and was Moore's off-screen boyfriend and then fiance, though they never wed. He also appeared in "The Breakfast Club" and the 1980s hit "The Outsiders." The son of Martin Sheen and eldest brother to Charlie Sheen, Estevez had roles in "Stakeout," "Young Guns" and "Mighty Ducks." He was married briefly to former singer, dancer and "American Idol" judge Paula Abdul and has also worked as a director.
|Rob Lowe as Billy|
In the 1980s, Lowe had the role of the bad boy of every teen girl's dreams down pat. He starred in "The Outsiders" and "About Last Night" with Demi Moore. But, in 1988, he became embroiled in sex tape scandal. In 2011, he told ABC News the scandal was good for him.
"It was very good for me because it began this series of sort of looking inward and trying to figure out what I am really doing with my life, which got me sober," he said.
By the 1990s, Lowe had gone to rehab for alcohol and sex addition and then married makeup artist Sheryl Berkoff. Since then, he's released a memoir titled "Stories I Only Tell My Friends." He's appeared in "The West Wing," "Wayne's World," the "Austin Powers" movies and TV's "Brothers and Sisters."
|Andrew McCarthy as Kevin|
McCarthy also starred in the 1986 hit "Pretty in Pink." He appeared in "Weekend at Bernie's" before hitting rock bottom. He entered a detox center for alcoholism in the early 1990s. Afterward, he appeared in "The Joy Luck Club" and traveled to Africa, South America, Asia and Spain. He married his longtime girlfriend Carol Schneider in 1999 and had a baby boy. Since then, he's starred in Steven King's "Kingdom Hospital."
|Judd Nelson as Alec|
He also appeared as rebel John Bender in "The Breakfast Club." Nelson has starred in "New Jack City," "Airheads" and had a notable role as the sheriff in "Jay and Silent Bob Strike Back." He also had a repeat role in the TV show "Suddenly Susan" and was once engaged to Shannen Doherty.

The actress has two Emmys and an Oscar nomination for the film "Georgia." She has released numerous folk albums and has appeared in "Turner and Hooch" with Tom Hanks and "Wyatt Earp," "E.R.," "Law and Order" and "Grey's Anatomy." She's currently starring in the off-Broadway production of "Tribes." She has five children.
|Ally Sheedy as Leslie|
Reportedly a ballet dancer and best-selling author before she started acting, Sheedy is best known for her roles in "The Breakfast Club" and "Short Circuit." In the 1990s, she battled a sleeping pill addiction and sought rehab. Her role as a drug-addicted photographer in the 1998 indie flick "High Art" won over critics.
