The father of two smiled happily and was in good spirits despite rumours he's having a difficult time with his ex wife Angelina Jolie and coming to a custody agreement of their six children.
The pair ended their marriage with a bitter split in 2016, with the custody battle over their children turning ugly.
His mother Jane Pitt believes "manipulative" Angelina is to blame for Brad's emotional turmoil.
"Jane is a tough cookie, and she will never forgive Angelina for what she’s put the family through – especially since they’ve barely seen the kids since the divorce was announced," a source told Radar Online.
"She thinks her son has been treated in a cruel and manipulative way, and she’s not letting this go."
"Brad’s had to beg his mum not to jump on a plane to confront Angie numerous times, but she wants to look her in the eye and give a piece of her mind," said the insider.
"She blames her for her ruining her son’s life and wants answers."
