When posed together, it's easy to tell the difference between Jenna Jameson and her half-nude wax look-alike.

Similarly, it's obvious that this Kylie Minogue picture is one of a fake version of the singer.

But looks can sometimes be deceiving. For example, take a look at Jessica Simpson below. Or, wait, is this a wax figurine of the large-breasted singer?

The giant boobs are certainly in place... along with everything else. Nothing is close to moving. Thanks to serious expression and smooth skin, it really is hard to tell if this is actually Jessica or just a statue.

But to remove all suspense, it's a photo of the actual former Mrs. Nick Lachey. It may not be as scary as old pics of Victoria Beckham - but we'll probably lose some sleep over it tonight at least.
