LOS ANGELES - Lindsay Lohan had words for her father on her blog.

The 22-year-old actress lashed out at father Michael by calling him a "public embarrassment" and a "bully" in a MySpace blog entry posted Thursday. Earlier in the week, Michael said in an interview with E! that Lohan gal pal Samantha Ronson was "using" his daughter.

Lohan's publicist, Leslie Slone-Zelnick, confirmed the post by Lohan was legitimate.

"If you have something to say to me, say it to my face -- that's what I have believed my whole life -- don't be a coward and say it to others first, let alone all the media in the world," Lohan wrote.

The father and daughter have publicly quarrelled for years. Lohan said in the hyphen-laden blog post that she tried to make things work in hopes "of having a father again" and "wanting things to change" despite what her mother and siblings have gone through with him.

Lohan continued: "Having said that -- the people were right, and he is yet to change -- but this time, without his daughter by his side -- 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)."

The "Mean Girls" star went on to say that she believes her father is addicted to fame, and if he really cared about her, he would respect her wishes. She also said than Ronson and Lohan's mother Dina would never "sell me out." Lohan ended the post by saying that she had a therapist and it's not a cameraman at x17 (the celebrity photo agency and website).

In a separate post, Ronson said she was angry when she first heard about Michael's attack on her and called him a man "who is so desperate for attention that he goes to the media whenever possible." Ronson went on to say she felt "no need to publicly defend my role in Lindsay's life -- I'm just sorry that she likes me more than him."
