Shia LaBeouf's recent erratic behaviour is reportedly down to a build-up of pressure from being a child star.
The actor's 2008 'Holes' co-star Siobhan Fallen Hogan believes his reckless actions have been spurred on his inability to deal with fame from such a young age.
Siobhan, who played Tiffany Yelnats in the Disney movie, told the New York Post newspaper: "I think there's a ton of pressure when you're in the acting business. It's hard growing up acting -- being a child actor. There's pressure to act the right way.
"And there's so much attention from the press that, if you make one wrong move, it's under a microscope. I can see that being hard for him."
The 'Transformers' star - who shot into the limelight at the age of 14 when he was cast in TV series 'Even Stevens' - was arrested at a Broadway theatre earlier this week for yelling offensive language and slapping people's bottoms during a performance of 'Cabaret' at Studio 54 in New York City.
Shia was charged with harassment, disorderly conduct and criminal trespassing, and is set to appear in court on July 24.
Earlier this month, the hunk was also reportedly banned from The Local Peasant in Sherman Oaks, California, after he was allegedly caught peeing up against a wall.
Meanwhile, earlier this year, Shia stormed out of a 'Nymphomaniac' press conference in Berlin, before arriving on the red carpet for the film's German premiere wearing a paper bag on his head that read, "I am not famous any more."

Kelly Osbourne has got a tattoo on the side of her head.
The 'Fashion Police' co-host, 29, who shaved off part of her luscious locks last month, shocked fans yesterday (28.06.14) after she revealed her new bizarre inking - which reads "stories..." in purple writing - on Instagram.
The beauty - who is the daughter of Ozzy and Sharon Osbourne - posted a picture of artist Dr Woo, from popular parlour Shamrock in Hollywood, completing the body art as she placed her hands on her stomach and carefully breathed through the excruciating pain.
However, Kelly was obviously pleased with her new look as she accompanied the snap with the cheeky caption: "Sorry mum and dad but I love it!"
Earlier on in the night, the bubbly star hinted that she was about to get a new tattoo after she posted a photograph of her holding a bottle of purple ink.
She wrote: "#oops what did I do tonight? (sic)."
Meanwhile, Kelly, who split from fiancé Matthew Mosshart in January, has reportedly grown close to Puff Daddy's stepson Quincy Combs, 23, recently.
A source said previously: "Kelly is single, but she's having a lot of fun. She's been hooking up with Quincy, her really good friend lately...
"It's not serious but he's really hot and he's very into her!"

Jessica Alba thinks it's "essential" to have date nights with her husband.
The 33-year-old actress has been married to her beau Cash Warren for six years, but she admits the pair regularly set time aside to enjoy each other's company.
When asked if she and Cash still go on dates, Jessica replied: "Yes! Absolutely. I think you have to. I think that's essential. [We do] anything. I mean, even watching TV and making popcorn. Other times having a 'staycation' and staying at a hotel down the street."
The 'Sin City' star - who has daughters Honor, six, and Haven, three, with Cash - insist they have a strong relationship because they respect each other.
She told Parade magazine: "You know, I think we have an incredible amount of respect for each other and we value each other's opinion and time, and I feel like we're in it together, we're not petty with each other, and we communicate a lot."
Meanwhile, the brunette beauty is busy juggling her acting career, motherhood and her eco-friendly business, The Honest Company, but she admits she has a fabulous team behind her to help her work everything out.
She explained: "It's hard [juggling my career]. I feel like I'm always compromising one thing over another. I have a really strong team at The Honest Company and my partners are incredible, so if I didn't have them to run the business when I'm not there, I'd be in trouble."

Beyoncé and Jay Z displayed Justin Bieber's mugshot during the opening of their 'On The Run' tour.
The couple have sparked controversy after they poked fun at the 20-year-old singer at their Miami concert on Wednesday (25.06.14) when they flashed his snap on a huge screen during a montage of celebrity prison photos.
According to fans at the show, Beyoncé reportedly made a subtle dig at the 'Baby' hitmaker as the infamous image popped up, and she said, "Even the greatest can fall."
However, the troubled star wasn't the only one to feature in the montage as stars such as Tupac, Robert Downey Jr, Russell Brand, 50 Cent and even Jay, 44, himself made an appearance on the large screen.
It was previously revealed the pair - who have two-year-old daughter Blue Ivy - also treated fans to never-seen-before footage from their wedding day in April 2008.
The intimate clip showed Beyoncé, 32, wearing a traditional white gown - which was designed by her mother Tina Knowles - and veil, with the rapper in a smart tuxedo as they exchanged vows and rings and had matching IV tattoos on their fingers.
Another video showed the couple walking down the aisle as watching guests threw confetti at them.
The footage was shown towards the end of the couple's 41-song set - which saw them perform both together and separately - as they sang 'Young Forever'.

Lucy Hale has split from her boyfriend.
The 'Pretty Little Liars' actress has called time on her short-lived relationship with country singer Joel Crouse after their busy schedules put a strain on their romance.
A source told Us Magazine: "Lucy and Joel are done, it was hard with the distance. She's working a lot on 'Pretty Little Liars' and on music -- she debuted at the Opry [in Nashville, Tennessee] over the weekend. It got to be too much."
The former couple first sparked speculation they were dating in April after they were spotted together at a Laker's game in Los Angeles.
The 25-year-old singer took to her Instagram account after the game to post a picture of her and Joel, 22.
She accompanied the snap with the caption: "First lakers game. Was really great teaching this one the rules of the game. And seeing him looking like a kid in a candy store @joelcrouse. (sic)."
The brunette beauty hasn't mentioned her ex-boyfriend on her social networking sites since June 15 when she wished him happy birthday.
She said on Twitter at the time: "Thank y'all for the bday wishes already. So kind. And also a huge happy birthday to Mr. @JoelCrouse see ya soon (sic)."

Dolly Parton received a surprise award at Glastonbury today (29.06.14).
The 68-year-old singer was presented with a congratulatory plaque by Glastonbury organiser Michael Eavis and her manager Danny Nozell at the Somerset event in honour of selling 100 million albums worldwide.
She said after receiving her award: "I've been so busy making records for the past several decades, I didn't realise I had racked up so many sales. What a great honour to know that I have so many fans that have supported me through the years.
"Thanks to the RIAA [Recording Industry Association of America] for the acknowledgment and the plaque. I feel very honoured and proud."
The '9 To 5' hitmaker took to the Pyramid Stage just two hours after being presented with the award to perform her energetic set in front of over 200,000 adoring fans.
The blonde beauty, who was dressed in a white suit covered in rhinestones, belted out the lyrics to her hits 'Islands in the Stream', 'Baby I'm Burning' and 'Jolene', before performing the title track from her new album 'Blue Smoke'.
The bubbly star even got fans to sing along to her new song 'Mud', which she wrote especially for the five-day music festival, before briefly dashing off the stage and returning with Bon Jovi's guitarist Richie Sambora for a duet of 'Lay Your Hands On Me'.
Dolly finished off her 70-minute set by thanking the audience for their continuous support over the years and then rounded off with 'I Will Always Love You'.

Lily Allen's baby daughter was struck down with a life-threatening illness.
The 'Hard Out Here' singer feared for two-year-old Ethel's life after she was diagnosed with laryngomalacia - a condition that causes the larynx to collapse into the airway - when she was just 12 months old.
Speaking on BBC Radio 4's Desert Island Discs, she explained: "It's [the illness is] basically a problem with the throat. She was working so hard to breathe, to just exist really, and she wasn't really gaining any weight at all.
"Because all of the food she was taking on, she was just expending the energy on this breathing process.
"I was scared of losing her the whole time, all I wanted to do was just breast-feed her and to sit there in my chair with her and spend those precious hours into the night looking after your child."
The 29-year-old star - who also has 16-month-old daughter Marnie with her husband Sam Cooper - admits the treatment process for Ethel didn't run smoothly and she ended up being fed via a tube for eight months.
Lily - who suffered a stillbirth in 2010 - recalled: "When she was really, really little the doctors said she had to have an operation to correct it and then that didn't work so she had to have it again.
"And she was tiny, she'd lost so much weight and then as a result of that, because of what happened before with my previous [baby], it was just a really tough time."
However, the brunette beauty insists Ethel is "absolutely fine now".

Olivia Palermo has confirmed she's married.
The 28-year-old beauty tied the knot with German model Johannes Huebl - whom she has been dating since 2008 - in a romantic ceremony in front of their family and two friends at a quiet park in Bedford, New York, last week.
Writing on her official website OliviaPalermo.com, she explained: "We really wanted to keep this beautiful day very private and special to us and enjoyed the whole day with our family and two friends. Bedford is such an amazing and romantic countryside."
The former 'City' star looked stunning dressed in a cream cashmere jumper with scattered ostrich feathers and white shorts with a full tulle skirt overlay, which was created by favourite wedding designer Carolina Herrera.
The newly-weds and their guests then made their way back into New York City for a party to celebrate becoming husband and wife.
The couple had originally planned to tie the knot in St. Barts - where Johannes proposed last December - later this year, but brought the date forward as the model had been experiencing issues with his visa, which may have meant he would have had to leave the US sooner.
A source said previously: "They were planning a big wedding in the fall, but Johannes left Wilhelmina Models last year, and he currently isn't with an agency, and was told he would have to leave the US in September."

Ansel Elgort feared incurring Shailene Woodley's wrath on the set of their films.
The 20-year-old actor, who stars opposite the actress in 'Divergent' and 'The Fault in Our Stars', admits he almost didn't read the acclaimed book the latter film is based on before his audition but his co-star forced him to brush up.
He explained: "I was on set with her on 'Divergent' and she said, 'Have you read it yet?' I couldn't lie to her, I said, 'No, I haven't.' She said, 'If you show up for the screen test and you haven't read it, I'll be so mad!'
"I was like, 'Oh crap, I've got to read this otherwise she's gonna be annoyed with me the whole time!' "
Elgort read the novel, which follows the tragic love story of two cancer-stricken teens, and admits he was blown away.
He added to Bliss magazine: "I literally couldn't put it down, it was so great. I read it over two days, which I've never done - I don't even read books! That's my only downside ... well, one of my downsides."
Having starred in two book adaptations this year, the hunk admits he'd prefer to write a novel like 'Fault in Our Stars' rather than a big sci-fi adventure like 'Divergent'.
He explained: "I don't know if I could write a big, epic story like 'Divergent'. I'd probably write something more about real life."

Paolo Nutini gets irritated by airport security and baggage restrictions when he's on tour.
The 'Let Me Down Easy' singer, who often tours the globe and spends hours in airports, admits it angers him that he can't take certain things in his hand luggage and there are limits to what he can take on the plane.
He said: "Christ, the amount of time I spend in f***ing airports with plastic f***ing bags. 100ml, f**k off!
"I brought back this stuff for my sister, products, they cost a fortune, I forget about them and this guy lifted them out of my hand baggage, 'Aha, 150 mil!' And they were in the f***ing wrapper. I bet he took them home for his missus and got himself a nice wee night out of that. I had to buy them again!"
The star claims the quote that defines us is, "Unattended baggage will be destroyed."
He seethed: "Even if I was that f***ed up that I wanted to blow up a plane, do you think I'd put myself on the f***ing thing? Come on! And the ****s stand there with their false sense of authority tasting my f***ing toothpaste?"
Despite being annoyed by airport security and baggage rules, one thing that doesn't irritate Paolo is having to pay his taxes.
He explained to Q magazine: "The best thing you can do is pay your taxes. People paying their taxes helped my grandmother stay a part of my life. She had various cancers, if it wasn't for the NHS I wouldn't be able to sit with her and watch Bradley Walsh on 'The Chase', one of my favourite things I can do. I've never had a problem with paying my taxes."

Rita Ora and Laura Whitmore are among the stars who have been sporting new Beats by Dre accessories at Glastonbury.
The headphones brand has teamed up with British fashion designer Henry Holland to create a strap for the Beats Pill XL, a wireless speaker which creates a summer sound system.
He has designed the accessory - which carries the Beats Pill XL and holds lighters, money, iPhones and every other summer essential, making it perfect for festivals.
'I Will Never Let You Down' hitmaker Rita was spotted with one backstage at the Worthy Farm event blasting out Blondie's 'Hanging On The Telephone' and got her crew to join in a sing-along to the song.
The strap accessory combines faux fur with snakeskin print leather and it's one of summer 2014's festival must-haves.
Speaking about the collaboration, Holland said: "The best thing about the Beats Pill XL is that you can take it anywhere so why not carry it like a fur trimmed accessory? I can't wait to see them anywhere there's music and sunshine."
The collaboration comes after similar projects with Fendi and Alexander McQueen.
The limited edition strap goes on sale tomorrow (30.06.14) and the Beats Pill XL is available now.

Jean Alexander has revealed her health scare was a stroke.
The 'Coronation Street' legend - who was taken to a hospital in Southport, Merseyside, by ambulance on Monday (23.06.14) - has told fans not to "worry", because explained the extent of her illness.
In a message on her website, she wrote: "Don't worry, I'm fit and well. I suffered a slight stroke but I am eating, sleeping, walking and talking.
"It's left me a little tired. I have always been a determined little bugger and hope to be back in the garden in no time."
The actress - who played cleaner Hilda Ogden for 23 years until 1987 - described the scare as a "hiccup" which is "to be expected" as she gets older.
She added: "This is just a hiccup, it's to be expected at my age. Don't write me off just yet."
Speaking earlier this week, her brother Kenneth Hodgkinson had said she was "reasonably chirpy and not in danger".
He said: "We don't think it is serious, she is getting on very well.
"She has left the hospital now and is in rehabilitation, a home, just for a week or so.
"She seems reasonably chirpy and not in danger. From what I hear she is pottering about and so on. It seems to have passed over."
