The actress claims her PC was stolen at the airport in Shanghai, China, and tweeted she was offering a reward for anyone who could return it.
Now TMZ alleges they know why the 27-year-old is so keen to get the gadget back.
"Why, you ask, is she so freaked out? We've learned she had a bunch of nude photos of herself," the website writes.
"She claims they're all from various photoshoots that were never supposed to be released."
In addition to the supposed naked pictures, there is allegedly also "private correspondence" from fellow celebrities stored on the device.
According to TMZ this includes messages from Woody Allen and Lady Gaga, which Lindsay is desperate to keep hidden.
She tweeted about the alleged theft on Tuesday, but later deleted the post.
"It was great to be in China and I want to thank everyone for their hospitality, however someone has stolen my computer at the airport… offering a reward for anyone who can retrieve and return it, bummer to go home without it (sic)," she wrote.
Lindsay had flown to Shanghai to attend the 2nd Sohu Fashion Achievement Awards.
The star is currently filming a reality series for talk show queen Oprah Winfrey’s TV network OWN at least two days per week. The programme is scheduled to air sometime this year.
Last month Lindsay was also offered a recording deal with label SMH Records.
She has already released two studio albums, including 2004 LP Speak and her 2005 effort A Little More Personal (Raw).
