Daddy Lohan -- LiLo's Just Making Sam Noise

It's just the gift every dad wants -- being accused of fathering a child outside his family.

And yet that's what Lindsay Lohan did yesterday, accusing her dad Michael of having another child besides herself and her siblings. But Michael's calling BS on the whole thing –- as in, he tells People the MySpace post may have been written by Samantha Ronson. He thinks the likelihood is "99 percent" that Sam penned the poison post.
