The 41-year-old actor shared a shirtless throwback pic of himself on Thursday, in which he explained how he needs to get back into working out and having a healthier lifestyle.
"#tbt capetown ‘Brian fit’ for #zulumovie this photo saved not JUST for vanity ? but as a lil reminder that I got to that place and I know how to get to that place when I need to go to that place ??," he captioned the Instagram snap. "Diet-lifting-hours of #nopainnogain and a #mindfulness presence and #focus that just won’t settle?? nothing but respect for those who can maintain it I try to stay close which is good because im heading back in that direction for Killer Joe soon to be at the @trafalgarstudios 18th may ??????."
Perry took notice of the photo and not only liked it but also left a great comment admiring her former beau's abs.
"Oh hey! I was actually looking for a washboard to be me laundry on," the "Firework" singer wrote.
Meanwhile, a source told ET last month that the two aren't just "hooking up" but also spending some time away from the public eye together to work on building a stronger relationship.
“The time they spend together alone is a way for them to build a new healthy relationship that is not under the eyes of their fans and the world," the source shared. "They both live very busy lives and have carefully made a plan to give their love a second chance."
