Here's something you don't read every day, a good news Lindsay Lohan story. Reports from the set of Charlie Sheen's show Anger Management say that Lindsay was on her best behaviour while filming.

The 26-year-old actress - who was sentenced to 90 days in a rehab facility last week for lying to police about driving during a car crash last June -  apparently 'shocked' crew members by showing up early on set in recent days and being extremely professional. According to Us Weekly 'She has showed up on time and early, and she has been very prepared and professional. Everyone is shocked -- the crew had already planned to stay late in case she was late or didn't show up, but so far, so good!'

Playing ball and doing all sorts to redeem her image, LiLo also took some time away from filming to meet a crewmember's children. 'Lindsay said, 'Oh, I'd love to meet them!' She went over and said hi and was really sweet to them.' Has she finally detoxed her ego perhaps? The actress filmed a guest role for the show this week after being invited to do so by her good friend Charlie Sheen, he who helps her out of financial woes at the drop of the hat and wants to be her 'mentor', even though she'd rather run a mile then let that happen.

But thanks to her good behaviour, there's a possibility she will be back on the show again once she completes her court ordered rehab and 30 days of community service, with insiders saying: 'She is only in one episode but is hoping to do more. There is a possibility she'll be asked back.' Lindsay herself tweeted about enjoying it saying 'I just had such a wonderful day on set of #angermanagement with @charliesheen & @LIGHTAARON @SaveTheSociety @jazejazz7 and the entire crew!'. Fingers crossed she's turning it around, but how many times has this happened before.
