Psst! Does Lindsay Have a Secret Sis?

Sometimes we can't verify a story, but it sounds so good we just have to share. We don't know if this story is true, but folks are talking about it and we want you to know about it!

OK, this is getting too weird. First, Ashley Jensen (you know, Christina on "Ugly Betty") finds out that she has a secret half-sister that her dad never told her about. And now, Lindsay Lohan may be getting the same news!

LiLo's dad, Michael Lohan, recently revealed to OK! magazine that he had an affair while he and ex-wife Dina were separated. And the other woman -- dun, dun, DUN -- got pregnant. But then Dina and Michael got back together -- at least for a little while. "Years later [the woman] contacted me, convincing me that I was the only person she was with and that she had my child," Michael told OK! in a statement.

The magazine also claims that Michael sent letters to the woman noting how much his secret daughter "is beginning to look a lot like Linds, with a mix of [younger brother] Cody, believe it or not." And, OK! reports, Michael sent the girl a picture of himself from prison, signed "Love Daddy."

It seems Michael has been reaching out to his alleged daughter, even calling her for her 13th birthday earlier this month. But the girl's mother claims that Michael has never visited her, nor provided financial support. "It's time for Michael to take responsibility," the Lindsay look-a-like's mom told OK!

This should add an interesting twist to the current battle between Michael and Dina over custody of their two youngest children, Ali and Cody. Talk about fodder for Dina's E! reality show...

And maybe Ashley will have tips for Linds on the set of "Ugly Betty" this fall? Have you ever found out about a previously-unknown family member?
