Justin Theroux appeared to slam wife Jennifer Aniston's ex-husband Brad Pitt in an expletive-filled post on Instagram.
The Girl On the Train star took to his social media page to comment on the upcoming presidential race between Hillary Clinton and Donald Trump by sharing one of street artist Nick Flatt's images.
In the picture, a woman can be seen flipping the bird as she bites on her middle finger, while surrounded by a wide array of expletives.
Among the words are "F**k politics", "F**k imperialism" and "F**k war", but fans were quick to comment on the most eye-catching of messages in the post - "F**k Brad Pitt".
Justin's post caused a frenzy on Twitter, with fans interpreting it as The Leftovers actor throwing shade at Brad and his recent split from Angelina Jolie.
Brad's romance with Angelina was famously sparked when they starred together in 2005 movie Mr. & Mrs. Smith, while Jennifer was still married to the actor. While all parties have always denied anything happened between Brad and Angelina until he had ended his relationship with Jennifer, the former Friends actress was always seen as the spurned party.
So when Brad and Angelina announced their split in September (16), many speculated that Jennifer would have been in her element, with memes of the actress looking delighted in scenes from her films and television shows quickly becoming viral.
However, Jennifer's close friend Chelsea Handler hit back at claims her pal had any kind of feelings about Brad and Angelina's split.
"It's so stupid and pathetic," Chelsea told Grazia magazine. "As if Jen cares - she doesn't care. Hello! As if she (Jennifer) is sitting around even caring about this."
Chelsea has never been one to censor herself, and labelled Angelina a "f**king lunatic" when she addressed the showbiz world's biggest ever splits on her Netflix show Chelsea.
"There are rumors that part of problem was that Brad was allegedly drinking and smoking too much weed. I wonder why he needed to self-medicate,” she said. "Maybe because he could have been spending the last 12 years at Lake Como, hanging out with George Clooney and Matt Damon, instead of being stuck in a house with 85 kids speaking 15 different languages.
"Oh yeah - because he married a f***ing lunatic, that’s why."
