Fans quickly noticed that Hailey liked a photo on Elle's Instagram account of the performer's cover, sharing some subtle support for the 29-year-old singer.
Hailey and Selena have been pitted against one another ever since the 24-year-old model rekindled her romance with Justin, which eventually led to the pair tying the knot in a courthouse ceremony in 2018.
In 2019, Hailey responded to headlines speculating that she was sending pointed messages to her husband's ex after the release of Selena's song, "Lose You to Love Me," which some fans thought was about her prior on and off romance with Justin. However, after seeing one article that she did not like, Hailey responded, writing, "Please stop with this nonsense…there is no 'response.' This is complete BS.'"
She addressed the rumors again in British Vogue later that year, saying, "I think social media is a breeding ground for toxicity and people creating false drama between women and trying to put women up against each other and create these narratives that are just... toxic. I think that has to change and that has to stop."
