Justin Theroux is reportedly dating 25-year-old artist Petra Collins, according to a new US report. A source told Star magazine: “Justin and Petra have been carrying on for some time. He insists that they’re just ‘friends,’ but he seems obsessed with her, and Jen isn’t buying it.” The pair met on the New York art scene and “hit it off right away” according to the same source, who also says they’ve “gone out on cosy dinner dates.” They are yet to be pictured together, but last month Justin tagged Petra into one of his Instagram posts. Interestingly, Petra was best mates with Selena Gomez - who is also famously very close to Jennifer Aniston. But today Selena unfollowed Petra on Instagram, which we all know is a sign of a friendship being over. The former BFFs had been really tight since 2015 with Selena even saying she was like a “sister”, but Selena's social media snub suggests they're done. Selena’s friendship with Jennifer Aniston has been going on a lot longer and before she even met Petra, the singer gushed about how Jen gave her “maternal advice”.""
