Lindsay Lohan has posted a shock X-rated photo of herself on Twitter.

The pic shows the star sans her bra with the caption: “OLD PHOTOS. I’m THAT bored.”Jeez Louise. If this is what happens when Linds is just bored, what about when she’s totally fed up?Will she strip naked and run down the street, we wonder?

Meanwhile, Lindsay’s rep has given an exclusive response to Sky Showbiz about the £250,000 jewellery disappearance that the actress has been linked to in London.

Scotland Yard has confirmed they are investigating the theft of Dior jewellery which went missing after a photo shoot Linds did for Elle magazine in the UK capital on the 6th June.

The 23-year-old’s rep told Sky Showbiz: “Lindsay did a photo shoot for Elle in London over a week ago, two days later there was a call from the editor of Elle saying that some jewellery went missing from the shoot.

“The editor said that Lindsay may get a call about it as will the other 15 or so people who were at the shoot – hair stylists, photographers, make-up people.

“Lindsay has not yet had any call from Scotland Yard.”The story is a bunch of crap,” the rep continued. “We have no idea why this story has legs and why people are making a big deal out of this and naming Lindsay.

“If Lindsay was a model would there have been such a big issue about it? No – it’s because Lindsay’s famous. It’s a bunch of lies yet everyone’s talking about it.”

A spokesperson for Elle UK has also released a statement which reads: “I can confirm on behalf of Elle magazine, that items of jewellery went missing from an Elle photo shoot… and the matter is now being investigated by the police. Elle has no reason to believe that Lindsay Lohan was in any way responsible and has no further comment to make.”Check out the latest pic of Lindsay in our gallery of the star over time, below.
