This is how Brad Pitt celebrated his 53rd birthday

Los Angeles: Hollywood star Brad Pitt reportedly celebrated his 53rd birthday on December 18 with close friends.

The actor, who split with wife Angelina Jolie in September, enjoyed a low-key dinner with his buddies, reported Hollywood Life.

"Brad Pitt spent his birthday enjoying a mellow dinner with a few close, old friends. Brad has been working hard on maintaining a low-profile and his plan is to stay out of the spotlight until his divorce and custody issues are finalised," a source said.

"He was not interested in celebrating his birthday out at any hot restaurants. Brad will not be doing anything that will interfere with his custody battle. His primary focus right now is working on himself and working on rebuilding his relationship with his kids," the source added.

Meanwhile, Jolie took daughter Shiloh, 10, camera shopping on Pitt's birthday.
