Shia's lawyer, Shawn Holley, tells TMZ, "Shia needs help and he knows that." Holley, who first told Variety about Shia's intentions, adds, “We are actively seeking the kind of meaningful, intensive, long-term inpatient treatment that he desperately needs."

This isn't happening in a vacuum. This comes shortly after ex-GF FKA Twigs sued him for physical, emotional and mental abuse.

She claims Shia once tried to strangle her after slamming her against a car. She says there were other incidents of violence ... she says he once pulled out a gun and told her he had killed stray dogs in the past because he wanted to know what it felt like to take a life.

Shia, who has struggled with addiction for years, had his name removed recently from a Netflix awards consideration page.
