The last time she appeared on the small screen, it was to star as Elizabeth Taylor in the critically panned Lifetime biopic Liz & Dick.

So Lindsay Lohan will be hoping that her latest foray into television – playing herself on Charlie Sheen’s sitcom Anger Management -  will be more successfully received.A new photograph from the set shows Lohan showing off her cleavage in a low cut lacy bra as she snuggles up to Sheen between the sheets. The actress has a coy look on her face as she lays her head down on Sheen’s bare chest, while he has his eyes closed with an arm wrapped around her shoulder.

Lohan filmed her scenes on Sheen’s show on Monday and Tuesday this week.According to Zap2it.com, she plays a version of herself who ends up being counselled by Sheen’s therapist after starring on a commercial for a Japanese gum called Number One Happy Whiskey Chew.The gum tastes like alcohol but contains no booze.A still shows Lohan dressed in a school girl style sailor outfit with strawberry blonde bunches, midriff bearing shirt, mini skirt and stockings as she ‘films’ the commercial.

However, Lohan is unhappy at being portrayed in the advertisement as ‘some drunk girl that hooks up with strangers and animals,’ so ends up in Sheen’s therapy room.The pair’s romantic tryst probably doesn’t end too well however, with Lohan only appearing in one episode of the show.Other behind-the-scenes shots feature the actress sporting a black T-shirt emblazoned with the slogan Therapists Do It On The Couch as she leans in for a smooch with Sheen.

She changes into evening attire with a one shouldered sparkly top and floor length black skirt, with her hair in a loose updo for another scene.The star’s scenes also appeared to show her visiting inmates in jail, perhaps poking some gentle fun at some of her recent legal woes.Lohan is reported to have been a model professional on her first day on set, with a source telling E! Online: ‘The first day was fine. She showed up early and did her job.’Another insider told TMZ: ‘Lindsay knew her lines cold and her timing was perfect. She was really funny.’

And apparently the actress ‘proved she has talent,’ according to the source. ‘You watch her and you know why she became a star.’However, the insider claims Lohan – whose episode will air next month – let herself down on her second day.’She was a colossal pain in the a**,’ the source said. ‘It’s a shame, because when she actually gets on camera she is good and has comedic timing. But she comes with so much luggage it’s not worth it.’

‘From the moment she arrived yesterday she did nothing but hold up the production,’ the insider added.  ‘She would sit in her trailer and stall and she delayed until she up and left for her boyfriend’s concert. She held everyone hostage.’But another source from the actress’s camp refuted the allegations and told E! News that Sheen was ‘happy with the actress’s work and any insinuations that Lohan deliberately held up the production were wholly untrue.’E! first reported that the star had to film for a ‘couple hours’ on the set on Wednesday after running behind schedule the previous day.

Lohan seemed to have a great time in her first acting gig since appearing in court last week.She tweeted: ‘I just had such a wonderful day on set of #angermanagement with @charliesheen & @LIGHTAARON @SaveTheSociety @jazejazz7 and the entire crew!’A  representative for Sheen had no comment, but the star has spoken out as to why he remains one of Lohan’s biggest supporters.’There is a reason that I root for [her], because we fell in love with this little girl that was just an absolute genius and had this great light about her and that’s still there,’ he told Entertainment Tonight.

Sheen, who once loaned the troubled actress $100,000 to help pay off her tax bill, revealed he is still worried about Lohan.’You have to be. But I think she seems a lot more focused now than she was five, six months ago. You can’t extinguish that. I root for her because when you’re that talented it just doesn’t go away. Sometimes your appetites get in the way.’The bad boy actor also agreed that he could relate to Lohan’s battles with substance abuse and legal issues.

‘Hell yeah,’ he replied. ‘But I, not to insult her because I’m who I am and she is who she is, I got things a little bit quicker or had better opportunities, better timing. They let me off the hook a lot sooner then they seem to want to do with her.’After filming on Anger Management, Lohan jetted off to Sao Paulo on Wednesday for a whirlwind promo trip, days before her court-ordered rehab.The star will soon be starting her 90-day sentence in a rehab facility, but is clearly doing her best to make some quick money before she starts.

She is reportedly in South America to make a six-figure sum by promoting a Brazilian clothing label.Clearly the chance of a big – and easy – pay day put Lindsay in a good mood as the star even managed to crack a smile as she arrived at the airport.Lohan – who recently started dating New York musician Avi Snow – does not have long left to make money before she goes into lockdown.Earlier this month the actress was sentenced to 90 days in a in-patient rehab facility for lying to police about driving during a car crash last June.

Meanwhile, it has been claimed that Lohan has found an unlikely ally in Twilight star Kristen Stewart.According toThe New York Post, the stars have been ‘hanging out’ after meeting through a mutual friend.’Lindsay was invited up to Kristen’s house last week, and they hung out with Robert Pattinson, who was back from filming in Australia,’ a source told the newspaper. ‘Lindsay and Kristen discussed their careers, creative ideas and how they deal with living under the focus of the media and the paparazzi.’ – DailyMail
