Ben Affleck revealed Tuesday he has completed treatment for alcohol addiction at a rehab facility.
The Hollywood A-lister, who sought help for alcohol abuse back in 2001, was last seen in public when he attended the Academy Awards on February 26.
Affleck, who shares three children with estranged wife Jennifer Garner, described the secret stint as 'the first of many steps being taken towards a positive recovery.'

Went public: The Hollywood star announced the news via a statement posted to his Facebook page
In a statement he posted to his Facebook page, the two-time Oscar winner said: 'I have completed treatment for alcohol addiction; something I've dealt with in the past and will continue to confront.'
'I want to live life to the fullest and be the best father I can be. I want my kids to know there is no shame in getting help when you need it, and to be a source of strength for anyone out there who needs help but is afraid to take the first step.'
Affleck, who separated from Garner in 2015 but never divorced, thanked his 'co-parent' and his friends for standing by him.
'I'm lucky to have the love of my family and friends, including my co-parent, Jen, who has supported me and cared for our kids as I've done the work I set out to do,' he wrote.

According to Entertainment Tonight, Ben was accompanied by a sober coach to the Oscars this year - where he watched his brother Casey take the Best Actor gong - to make sure he didn't drink.
The 44-year-old actor is believed to have invited a special recovery professional to the Dolby Theatre in Los Angeles to ensure he remained tee-total for the evening.
The dark-haired hunk decided to cut the booze for himself and for his family because his brood has 'always' been his priority.
Speaking about the 'Live by 'Night' star and his treatment, a source said: 'He has completed his treatment and is feeling good. [He] did this for himself and his family. Family always comes first.'
The source explained: 'Ben has struggled with alcohol for years and it's a struggle that millions of people have to battle every day. He has nothing to hide and wants his kids to know that he did everything he could to be a better father. That's why he announced it himself.'

Affleck, 44, and Garner, also 44, are parents to daughters Violet, 11, Seraphina, eight, and son Samuel, five.
The actor knows from personal experience how having an alcoholic in the family can effect children.
His own father Timothy struggled with addiction and split from Affleck's mother Chris when the actor was 12.
'It was difficult,' he recalled in an interview with The Hollywood Reporter in 2012.
'When one's parent is an alcoholic, it's hard. It was a little scary and trying, but then he got sober when I was twentysomething, and he's been sober ever since.'
Focusing on fatherhood: The actor, 44, whose own father was an alcoholic, said he was motivated to seek treatment so he could be 'the best father I can be' to his three children, Samuel, five, Violet, 11, and Seraphina, eight, pictured with him in December
Having issues: In January, Affleck was spotted out in Beverly Hills with Elizabeth Weaver, who offers sober living companionship through her company Concierge Nursing Care
In 2001, four years after he and Damon had exploded onto the Hollywood scene thanks to Good Will Hunting, which earned them each a screenwriting Academy Award, Affleck went to rehab.
'I went to rehab for being 29 and partying too much and not having a lot of boundaries and to clear my head and try to get some idea of who I wanted to be,' he told The Hollywood Reporter.
'It was more a 'let me get myself straight,' before it became a rite of passage,' he explained.
Heady times: Affleck found fame with the 1997 film Good Will Hunting which earned him and co-star Damon an Academy Award each for original screenplay. Four years later he voluntarily entered rehab for, he said in 2012, 'partying too much and not having a lot of boundaries'
There were rumors Affleck was having issues with addiction again back in January when he was spotted out and about in Beverly Hills with sober living coach Elizabeth Weaver.
The pretty blonde founded Concierge Nursing Care that offers 24-hour medical in-home detox care.
He also recently announced he would no longer be directing The Batman, in which he will reprise his role as the Caped Crusader in a standalone follow-up to his Batman v Superman: Dawn Of Justice hit.
He also dealt with disappointing reviews and poor box office for his most recent film Live By Night which he directed and starred in.

Out and about: Garner, 44, was seen running errands near the family's Pacific Palisades home on Tuesday as news broke of her estranged husband's rehab stint
While he was in rehab, Garner, whom he wed in 2005, enjoyed a mini break in Mexico with some galpals over the weekend.
On Tuesday, though, she was seen running errands near the family home in Pacific Palisades as her estranged husband shared his news with the world.
The actress looked serious as she stopped to pick up a magazine wearing skinny jeans and flip-flops with a gray cardigan buttoned up over a striped shirt.
She and Affleck broke the news they planned to divorce on June 30, 2015, one day after their tenth wedding anniversary.
One month later, the couple's former nanny Christine Ouzounian, 28, claimed to be having an affair with the Armageddon star. It's something he has consistently denied.
In an interview with Vanity Fair, Garner said that their decision to separate had nothing to do with Ouzounian.
'We had been separated for months before I ever heard about the nanny. She had nothing to do with our decision to divorce. She was not a part of the equation,' the Alias star insisted.
