Lindsay Lohan had nude pictures saved on her missing computer.

The 'Mean Girls' actress has issued a reward for the return of her laptop, which she claims was stolen from an airport in China on Tuesday (07.01.14). and is said to be desperate for it to be returned because of the confidential files she has stored on there.

According to gossip website TMZ, Lindsay has naked pictures of herself from photoshoots that were never meant for release, and also

''private correspondence'' from famous people, including Woody Allen and Lady Gaga, that she wants to be kept secret so is offering ''whatever it takes'' for the computer to be returned safely.

And it is likely the 27-year-old star has work documents on the laptop as it was recently revealed that Lindsay is working on her third studio album and is also writing her memoir.

Although the book is in its early stages, Lindsay started it as a series of journal entries while in rehab last year.

The book is expected to see the 'Machete' actress open up about every aspect of her life including becoming a child star, allegations of drug use, relationships with famous people - including her relationship with Dj Samantha Ronson - legal troubles and rehab stints.
