Lane Garrison Released from Jail ... Finally

Former "Prison Break" star Lane Garrison has finally bailed out of jail after being locked up for more than 2 months.

Lane was arrested April 22nd after allegedly striking his ex-GF in the face during a blowout fight in Beverly Hills -- and has remained in custody ever since because he was on a parole hold for his 2007 vehicular manslaughter conviction.

Lane posted $50,000 bail and the jail doors opened.

He's due in court July 11 for a hearing in the domestic violence case. He pled not guilty and claims he never struck his ex-GF.

TMZ posted surveillance footage of the April fight -- which appears to show Lane hitting Ashley Mattingly in the face.
