PHOTOS: Lindsay Lohan in 'Anger Management'

We're more used to seeing Lindsay Lohan in a state of dishevelment given her ongoing travails with the law, but new photos show the troubled actress resembling something of her former self.

Released by US TV network FX, the shots show LiLo onset with pal Charlie Sheen during a taping of Sheen's series 'Anger Management'

Lohan guest stars as herself as a patient on the comedy, which stars Sheen as an anger management therapist. The episode airs on April 11 in the US.

Filming on the show went well, by all accounts, with 'Anger Management' insiders saying Lohan was a pro to work with.

It comes after LiLo was sentenced to 90 days in a rehab facility on March 19 for lying to police about driving during a car crash in June 2012.

Lohan and Sheen are good pals, with the latter no stranger to controversy himself.

The duo became firm friends after filming a cameo for 'Scary Movie 5' last year and Charlie, who has repeatedly supported the actress, even gave her $100,000 to pay a tax bill.

However it may be that her good behaviour stint was short-lived. The 26-year-old has since raised eyebrows with a whirlwind weekend of partying in Brazil (including obligatory wardrobe malfunction) and the below tweet yesterday…

Given the date, we are assuming she was joking…
