Lindsay Lohan claims an "old friend" is responsible for the burglary at her home.

The 'Mean Girls' actress, who is devastated by last weekend's break-in at her Los Angeles home, made the accusation on her Twitter blog.

It was originally claimed the 23-year-old star returned home to find her safe ripped from the wall and various shoes, bags and jewellery missing.

It has since been reported the safe contained incriminating videos and photographs that could cause embarrassment if they are made public.

Lindsay's father Michael and mother Dina have both publicly spoken out following the break in, with Lindsay admitting she is too nervous to return home.

She wrote on Twitter: "i'm sorry i haven't been on in a bit... my life has been kind of in shambles considering my house was broken into and i feel really violated

"it really makes me sad, and well, obviously-scared (sic)."
