Parents are embarrassing at the best of times, and then there's Michael Lohan.

Of his daughter's girlfriend, the failed actor said: "Samantha drinks and passes the drinks under the table to Lindsay and behind the scenes it gets worse and worse. Sam is using my daughter. My daughter isn't working because she’s always with Sam. Even my ex-wife knows it. She just isn't doing anything about it... I’ve shut up about this long enough. She’s using my daughter. People never even knew who Samantha Ronson was until she met Lindsay. She was just some Los Angeles DJ. And now she’s writing a book? I am at (my) wit’s end with this stuff, This is not in Lindsay’s best interest. Let’s just say I hope Lindsay starts opening her eyes and realizes (sic) who the people using her are."

Instead of going down the route of dignified silence, Ronson posted this on her blog yesterday: "SHUT THE F**K UP... I really don't want to say anything because I feel like he wins - he, being the man who is so desperate for attention that he goes to the media whenever possible - I know that I am being used, I am just a pawn - easy to sacrifice in order to feed his addiction. I was angry when I first read his attack on me, but for me, I believe that actions speak louder than words… so now I just pity him - I am not standing in his way - I am not the reason that he has no contact with his daughter - he is - his need to throw a tantrum for the whole world to hear is. I am not going to go into a play by play defense (sic) - I feel no need to publicly defend my role in Lindsay's life - I'm just sorry that she likes me more than him. P.s. I'm not the one that is so lost that I need to use my relationship with Lindsay to earn a living… I am, always will and always have been here for her - not for anything else…so I think it’s safe to say that there is not now and never will be a tell all… written by me… when does your book come out Mr Lohan?"

Then it was Lindsay's turn to post on her MySpace, saying: "He has become a public embarrassment and a bully - to my family, my co-workers, my friends, and a girl that means the world to me. It’s obvious who that is. He has no idea what is going on in my life because I have chosen not to involve him in it. His recent attack on my life and my loved ones is simply for an ADDICTION THAT HE HAS - FAME. Why he feels the need to comment on anything in my life that I may want to keep private is beyond comprehension. If he really cared about me and my life, then he would learn to respect my wishes by staying out of it... BFF Samantha Ronson has not and would never sell me out. Nor has my mother, who is wonderful."

As much as it unnerves to say, Lindsay comes across as the most together. She's even managed to include appropriate capital letters this time... unless Dina wrote it, which would account for the post's final bemusing line.
