Bruce Willis and Demi Moore's reportedly gave their daughter an "ultimatum" to check into rehab.
Tallulah Willis, who recently admitted she "struggled" with body dysmorphia and an eating disorder when she was younger, reportedly entered The Meadows facility in Arizona late last month after her famous parents insisted she sought help.
A source said: "Tallulah was pretty much given an ultimatum. Her parents were about to take away everything from her."
According to the insider, 20-year-old Tallulah - who is rumoured to be being treated for cocaine and alcohol abuse - was "adversely affected" by her parents' divorce and and another source claimed she struggled when Demi checked into rehab for "stress and exhaustion" in 2012.
The source said: "When Demi was hospitalised, Tallulah didn't show up to school for days because she was too embarrassed.
"She was very open about Demi's issues and would sort of imply, 'Of course I have issues too, look at my mom.' "
The fashion blogger's parents - who also have daughters Scout, 23, and Rumer, 25 - are said to have taken different stances on their youngest child's issues.
The source explained to People magazine: "If Bruce suspected that Tallulah had any kind of substance abuse problem, he would have demanded for her to get help.
"Demi's take is that Tallulah is still very young and trying to find herself."
Demi and Bruce, who also have daughter split in 1998 after 11 years of marriage.
The 'Die Hard' actor also has daughters Mabel, two, and Evelyn, three months, with wife Emma Heming.

Michael J. Fox was "stunned" to learn Robin Williams had Parkinson's Disease.
The 'Back to the Future' star - who was diagnosed with the condition in 1991 - hailed the late actor as a "true friend" and recalled all the work he did to raise money for his foundation, which raised money and awareness of Parkinson's, in a Twitter tribute.
Michael wrote: "Stunned to learn Robin had PD. Pretty sure his support for our Fdn predated his diagnosis. A true friend; I wish him peace."
Robin's wife, Susan Schneider, revealed yesterday (14.08.14) that the 'Hook' star was in the early stages of the disease when he took his own life.
Meanwhile, comedian Jeff Kilstein, 32, has spoken of how Robin - who battled alcohol addiction but got sober in 1982, relapsing briefly 20 years later - would help him whenever he was "struggling"
He told Us Weekly magazine: "Every time I struggled with addiction myself, or depression, or thought about quitting he would chat with me on the phone.
"I'd be sitting in my office and Robin Williams, in the softest voice, would just be helping me through it all. He would help me out of my darkest moments."
And Jeff revealed his friend - who was found hanged on Monday (11.08.14) following a long battle with depression - even paid his wages at one point when his radio show was struggling.
He recalled: "My radio show Citizen Radio had a moment where we almost had to stop because we were getting kicked out of our space.
"Robin heard about it through our mutual friends and called me, just saying, 'What do you need?' He made up the difference in my salary while we were struggling. Our inside joke was that we didn't have sponsors but we were brought by 'Robin Williams.' "

Elba, 41, said he was "disappointed" with some of the offers he has received in recent months.
He explained: "You know, I'd just played this iconic human being, and the scripts I got afterward were sort of ... disappointing ... Look, I know that I work a lot, but I'd prefer to wait sometimes because I don't want to just do rubbish films anymore or characters that anyone can play."

Professor Green has cut James Arthur from his album.
The 'Remedy' hitmaker - who is to release his third studio album 'Growing Up In Public' this September - was forced to drop the 'X Factor' winner from a track following a string of public controversies surrounding his use of homophobic lyrics and online Twitter rants, reports The Mirror newspaper.
Professor Green, 30, said: "James Arthur was on that record. But then he just kind of imploded, didn't he? It's a shame, when I met him he was a cool guy but he just upset so many people.
"The label was just like, 'It's not happening', and I can't fight the people who I need to support me."
However, the 'I Need You Tonight' hitmaker remains fond of James, 26, and hopes that the 'Impossible' singer will be able to get his career back on track.
He explained: "When I met him, I thought he was a nice guy, so hopefully he can just bring some of that back and get people to focus on the music and maybe he can too, rather than getting concealed by all the bulls**t."

The six-part series - which will return to its original home at the 2,200-seat Palladium theatre - also has a host of guests booked already, including comedy sets from Alan Davies, Sarah Millican and Milton Jones.
Gemma Arterton's new musical, 'Made in Dagenham', will be awarded a slot on one of the programmes, while a diverse bill of musicians have been booked, including Neil Diamond, Art Garfunkel, Bryan Adams, Maroon 5, The Script, Nicole Scherzinger and Little Mix.
An ITV spokesperson said: "Some of the UK's best-loved comics and entertainers will host one show each and introduce some of the biggest stars from music and comedy.
"There will be jaw-dropping acts from around the world, plus surprise guests."
'Sunday Night at the Palladium' pulled in highs of 28 million viewers during its initial run from 1955 to 1967.

Miley Cyrus reportedly "caused chaos" in a New York hotel.
The 'Wrecking Ball' hitmaker is said to have angered management and guests at the Greenwich Hotel when she stayed there on August 2 because she and her entourage were loud and "out of control".
A source told Life & Style magazine: "It was like a tornado hit the lobby. Miley and her posse took over, screaming and carrying on so much that management received a number of complaints.
"Led by Miley, someone in the group was smoking pot, and they were swearing loudly and throwing themselves all over the expensive furniture."
And the 21-year-old star reportedly told staff who asked her to be quieter they "should be glad to have her" because she has "spent so much money there".
According to the magazine, the hotel have asked fellow guests to file individual complaints about the singer so they can fully investigate what happened.
While the star hasn't commented on the claims, another insider insists they are false.
A source told E! News: "There were no complaints. Miley never had an outburst in the lobby."

Kendall Jenner's reputation is "everything".
The 18-year-old model has sent a cease-and-desist letter to waitress Blaine Morris after she claimed the reality star "threw money" in her face after she confronted her when she left New York eatery Mercer Kitchen without paying a bill and her mother Kris Jenner says Kendall took action because she won't allow herself to be bullied.
Kris said: "[Kendall takes things] very seriously and doesn't want people to walk all over her, and we go back to the thing of people who are bullies and do things that are not honest.
"Kendall's very serious about what people say and do and she considers her reputation everything and she feels like she did the most honest thing she could have done and was so nice--and by the way, Kendall lives very near this place and frequents this restaurant all the time and felt like she was in a real safe place."
The showbiz matriarch said the 'Keeping Up with the Kardashians' star "felt horrible" about the waitress' account of what happened because she is always so "respectful" to other people.
Speaking during a stint co-hosting 'E! News', Kris said: "If anybody knows our little Kendall - our tall Kendall - she's the most respectful little girl in the world and would never do anything like that.
"And once she realised what was going on she absolutely gave the woman the 30 dollars that she owed - or 33 dollars, plus a tip- and felt very horrible about the fact that somebody would do this and create these stories and start spreading things."

Fifi Geldof's depression hit her "full whack" following the death of her sister Peaches.
The 31 year old - who is the eldest daughter of Bob Geldof and the late Paula Yates - admits she has been able to "mask" the condition for some years but her problems have worsened since her 25-year-old sibling died of a drug overdose in April.
Writing on her Instagram account, Fifi said: "I wear a permanent mask so I won't feel judged for feeling how I actually feel.
"You can't escape it, it just simmers under the surface when it's not hitting you full-whack.
"Which, for obvious reasons, it has done to me for the last few months.
"People wouldn't have the first clue of it to look at me or talk to me, though."
Fifi's comments come just weeks after the inquest into Peaches' death found that the TV presenter - who was found on a bed surrounded by drugs paraphernalia - had died as a result of a heroin overdose.
The PR executive - who also has sisters Pixie and Tiger Lily - also felt the need to speak out following the news that 'Mrs. Doubtfire' actor Robin Williams took his own life earlier this week due to his struggle with depression.
She wrote: "Devastated by the news. Depression needs to be taken a lot more seriously.
"No one should feel pushed to those actions by their all-encompassing misery.
"Makes me so sad that he had the world crying with laughter whilst drowning in his own tears."
Fifi added: "I think this has prompted me to want to speak out publicly about my own depression which I've suffered from for years.
"Just in a feeble attempt to bring some more awareness and understanding to something that oughtn't to be surrounded by such a stigma."

Harry Styles has asked a fan to marry him.
The One Direction heartthrob popped the question to a lucky supporter who was dressed as a bride at the 'Little Things' hitmakers' gig in Philadelphia on Wednesday (13.08.14) after he picked her out of the sell-out crowd and joked he didn't want her efforts to go to waste.

"Now I feel bad letting this go to waste so what's your name? Preeya? Preeya ... will you marry me? There's been a plot twist! OK .. awesome."
The 20-year-old singer then joked that he and his new love were going to wait until everyone had sent them presents to celebrate their engagement before calling it off.
He added: "We'll take the engagement gifts and then we'll ... OK, awesome. I almost wore my wedding dress. It could've been awkward. But that's a different story."
Ladies man Harry has had several failed high-profile relationships with stars including Kendall Jenner, Caroline Flack and Taylor Swift.
Taylor appeared to make a dig at Harry - who she split from in January following a brier romance - at the Teen Choice Awards on Sunday (10.08.14) when she made a cheeky quip while introducing the Choice Actor in a Drama Movie category.
Speaking to the audience, the 24-year-old beauty said: "Oh, hey guys. You know we've had some amazing memories here together at the Teen Choice Awards.
"And so, I was excited when they asked me to come and present this award, because no one knows more about dramatic males than I do."
