Lohan's father says post was actually written by Samantha Ronson

Most people have abandoned MySpace for Facebook, but apparently what Lindsay Lohan has to say won't fit in a status update.

The actress took to her MySpace blog on Christmas day to compose a post entitled "Random Thoughts," where she disclosed that her father just let her family know that he has a child with another woman.

"He cheated on my mother and that really sucks ... MERRY CHRISTMAS!!!," the 22-year-old writes.

Lindsay's father Michael denies the claim, telling People magazine that he thinks there's a "99 percent chance" that Lindsay's girlfriend DJ Samantha Ronson actually wrote the entry.

Talk of a third Lohan sister is nothing new. Rumors began circulating early this past summer when a woman named Kristi Horn alleged that she has a daughter with Michael Lohan 13 years ago. Lohan said that he had had a relationship with Horn while separated from his wife -- Lindsay and Aliana's mother -- Dina. While he admitted that photos of Horn's daughter resembled his girls, no paternity test was taken at that time.
