A Lohan Family Christmas: Lindsay and Dad Michael Go at It Via the Internet

It was a  real Lohan style family Christmas, via accusatory blog posts and emails to gossip site TMZ, which has now come down to Lindsay Lohan's dad Michael Lohan throwing down threats and a gauntlet to Lindsay's girlfriend of more than a year, Samantha Ronson.

"My father just let my family and I know, amongst others that he had another child after my little sister Aliana, or maybe he had it before Aliana?? Either way, he cheated on my mother and that really sucks... MERRY CHRISTMAS!!! Wow- do I sound like "Debbie downer" or what? not trying to be..." Lindsay wrote in her blog on Christmas Eve, according to Perez Hilton.

Despite her anger with ex-convict turned conservative Christian father, Michael, Lindsay primarily took to her blog to congratulate Britney Spears for pulling it together and for her remarkable comeback.

Lindsay also noted that she was spending the holiday with Ronson and shouted out love and kisses to those family members she actually likes including her mother Dina Lohan and her sister Ali Lohan.

            But Lindsay's missive angered her father Michael who shot back at her via an email to TMZ, in which her referred to Ronson as the dark force in Lindsay's life, who's ruined his daughter's career.  He also accused Ronson of penning the blog post about his illegitimate child.

"What real work has Lindsay done since Sam? Maybe she should follow Britney or Drew's paths and get rid of the darkness and come into the light."

            Michael has threatened to release sordid information on Ronson if any further detrimental blog posts appear by either of them, threatening Ronson and throwing down a gauntlet in a fell swoop.

"If one more blog or statement is made people will know the entire truth. I will release emails, texts, depositions and audio tapes that will prove everything I have been saying all along. If Sam wants to play, I am ready. But she better be ready too!"
