Actress Lindsay Lohan on Friday struck back at suggestions she was shirking tasks assigned to her under a court-ordered probation, saying the media speculation to that effect has no truth to it.

The reports surfaced only days ahead of a progress hearing on her probation and resulted from Lohan switching her community service program after missing sessions at a Los Angeles women's shelter. The change was confirmed by a court official who declined to discuss details.

Lohan, 25, was sentenced to 360 hours community service earlier this year as part of her sentence for stealing a gold necklace from a jewelry store. The Mean Girls actress also served 35 days under house arrest.

The judge in the case warned Lohan to take the requirements seriously and complete her community service on time. If not, she might violate probation and be sent back to jail.

Lohan has until May 2012 to complete the program and is due to return to court on October 19 for a progress meeting.

Los Angeles District Attorney's spokeswoman Jane Robison said Lohan was now working with the Red Cross after several missed visits at the women's shelter.

Celebrity website TMZ.com said Lohan repeatedly failed to show up at the women's center and when she did, she stayed less than the required four-hour session.

Lohan, whose once promising movie career has been derailed by multiple trips to jail and rehab since 2007, did not address the allegations in detail. But she responded on Twitter saying: I am not to be made an example of anymore. I am working hard and fulfilling my obligations every single day, to the court as well as myself. If I travel, it's for work and it's been approved.

...I'd appreciate it if people will just let me do what is asked of me, so that I can get my life back. Please ignore the reports which have no truth to them, she added.
