Lindsay Lohan will reportedly seek a restraining order against her father Michael next week after his failed intervention with her

The 'Liz & Dick' star - whose father Michael staged an unsuccessful intervention with her on Friday (19.10.12) amid fears she is drinking and using drugs again - is said to be looking into filing a protection order against him.

A source close to the 26-year-old actress told gossip website TMZ that Lindsay feels the only way to stop her father from interfering in her life is to take legal action.

The troubled starlet - who recently cut Michael out of her life after he recorded their telephone conversation during which she was fighting with her mother Dina and made it public - will allegedly meet with a lawyer in New York next week and has the full support of Dina.

Meanwhile, fitness trainer Josh Chunn - who Michael claimed is dating his daughter and was present during his failed intervention - has opened up about his relationship with her.

He told the New York Daily News: "I've been trying to get Lindsay to focus. But how do you get her to focus with all the stuff going on around her? I can barely focus. She's a strong girl. She's cleaning up. I just want her to be OK.

He said: "I think I'm the best influence on her. The deal is she is surrounded by a bunch of f**k-ups.

"I'm there for Lindsay. I listen. I work hard for my money. I pay my own bill when we go out. I have a schedule. That's the problem with these kids in L.A., they don't have a schedule. All they want to do is party."

Lindsay dismissed rumours she has a boyfriend on Friday via twitter. She wrote: "I don't have a boyfriend. I have Chanel, Hermes and diamonds. X (sic)"
