Brad Pitt has made changes in his life following his painful split from Angelina Jolie, who filed for divorce in September 2016. The changes the War Machine star has made, however, has nothing to do with his divorce.

The 53-year-old actor is said to be working on his body, according to Celebrity Insider.

The Allied star is also living a healthy lifestyle while being single.

"He is happy, relaxed and is now getting familiar with his new life as a single man," a source told the celebrity news website.

"The way he looks is not a revenge body at all, he just wants to live healthy and be happy. And that is exactly what is happening and his body is benefiting from his healthy lifestyle."

Besides hitting the gym to get the chiselled look, Pitt has been working hard on his new hobby of sculpting. He was recently spotted outside his art studio in Los Angeles.

Speaking about a healthy lifestyle, Pitt has given up alcohol, which he has previously said was partly responsible for the collapse of his marriage to Jolie.

"I mean, we have a winery. I enjoy wine very, very much, but I just ran it to the ground. I had to step away for a minute. And truthfully I could drink a Russian under the table with his own vodka. I was a professional. I was good," he told GQ in an interview. "Don't want to live that way anymore," he added.

Pitt is said to be relying on the support of his friends Bradley Cooper, Thomas Houseago and George Clooney to keep himself from drinking.
