Lindsay Lohan may have some of her most prized possessions sold off if she doesn't pay her bills.

The 'Mean Girls' star's bill totals at around $16,000 after months of struggling to pay the storage company holding her valuables, and she could lose her personal effects in an auction if she doesn't hand over the money by the end of December.

The possessions in the locker include family heirlooms, designer clothing and ''potentially embarrassing'' articles about her, which Lindsay is now unable to access after falling behind on payments.

Gossip website TMZ reports that the troubled 26-year-old actress has turned to friends and family for help after her bank accounts were frozen by the Internal Revenue Service (IRS) over unpaid taxes for 2009 and 2010 - however, no one has come forward to offer their services.

'Anger Management' actor and close pal Charlie Sheen recently gave Lindsay $100,000 towards her massive tax bill - though she still owes around $8,000 rent for her Beverly Hills mansion - but was left astounded when she didn't even thank him for the generous gift.

He revealed: ''She got shorted and I found out, so I said, 'Here'. I'm still waiting for a text to say 'Thank you'. Anything you know?''

Lindsay has since enlisted the help of her younger sister Ali Lohan, 18, to help sell what designer clothes she has left to raise more money.

The star is facing more trouble as her probation was revoked on Wednesday (12.12.12) after she failed to turn up to court over three formal charges - including lying to the police.
