Is Ashley Kaufmann a Lohan?

Ashley Kaufmann, your worst nightmare might soon come true.

Celebrity gossip tabloid In Touch Weekly has published the first pictures of the 13-year-old girl who may be the spawn of Lindsay Lohan's father, Michael.

Ashley's mother, Kristi Kaufmann, has made just such a claim.

Is Ashley Kaufmann the half-sister of - gulp! - Lindsay Lohan?

At first, Michael Lohan admitted it. Now, he denies it. The ex-convict has submitted his DNA for a paternity test and has said that if Ashley is his, he' ll accept responsibility.

"I've seen pictures and, to tell the truth, there are similarities with Linds," Michael said.

There are? Really? We don't see cocaine residue anywhere on Ashley Kaufman, nor is she carrying around a bedpost on which she can carve a new notch every night.
