The star is apparently happier than he's been in years thanks to a new romance.
It has been reported that Pitt and Theron were friends prior to their alleged romance. Previously, Charlize was actually hooked up with actor Sean Penn.
Meanwhile, Brad's ex-wife Angelina Jolie is not Theron's biggest fan as the beauties are reportedly known enemies.
Theron is not the first person Pitt has been linked to since he split from Angelina Jolie in 2016.
The "Mad Max: Fury Road" actress has yet to meet Pitt's six children whom he shares with Jolie.
The couple finally came to a custody agreement in November 2018.
It looks like Brad Pitt is off the market again.
Charlize Theron arrives for the premiere of Netflix's "Girlboss" at ArcLight Cinemas in Hollywood, California on April 17, 2017.
A source has told the publication, "They have been casually seeing each other for almost a month now".
"ironically through Sean - but things have developed", a source blabbed to the publication. "She was on vodka cocktail while he stuck to mineral water".
The source didn't elaborate on the recent rumors that Angelina's ex and Charlize have embarked on a romantic relationship on top of their apparent professional one.
After being married for five years, Pitt and Aniston chose to separate and eventually divorced.
The supposed "turf-war" between the two actresses has been going on for years and "just won't stop" the Radar source claims.
Theron then began a relationship with Irish actor Stuart Townsend after meeting him on the set of the film Trapped.
The Oscar-winning actress ended her engagement with Sean Penn in 2015.
The pair were spotted together after attending separate movie screenings on Saturday. So they have spent time together.
