Bleary-eyed Brad Pitt was the last man standing at England’s annual Glastonbury Festival , putting both his sobriety and the custody of his kids in jeopardy!
What’s more, multiple spy witnesses claimed Brad, 53, cozied up to actress Sienna Miller, 35, as the sun rose!
A Radaronline.com investigation tracked the single dad after the festival to the Rabbit Hole nightclub on June 23 — where he partied it up until 3 a.m.
He’s also provided the court with voluntary drug tests to prove he’s on the wagon as he fights to spend more time with his six children.
An insider spilled: 'At this rate, Brad’s heading for a major relapse, and he’s only going to push Angie’s buttons if she thinks Brad’s flirting with Sienna.'
'Right now Angie holds all the aces in terms of custody, so Brad needs to keep on her good side.'
