Troubled star Shia Labeouf is reportedly taking his alcohol addiction therapy seriously as he does not want to look unfit in front of Brad Pitt during promotional events of their film 'Fury'.

The 28-year-old 'Transformers' star, who was arrested last month for his alleged disorderly conduct and harassment at a theatre, does not want top embarrass himself in front of the Hollywood superstar, reported The New York Post.

'Fury' is scheduled to come out in November and LaBeouf is reportedly worried about slipping up in front of Pitt while they do press and promotional events, a source said.
