Sofia Richie is only adding fuel to the rumors that she and ex-boyfriend Scott Disick have rekindled their romance. Richie wearing Disick's clothing brand is especially significant since his other famous ex, Kourtney Kardashian, recently made headlines for wearing one of the businessman's flannel shirts while on a joint family vacation. Disick and Richie dated for almost three years prior to their split. Disick still regularly appears on Keeping Up With the Kardashians, and the Kardashian-Jenner family recently threw him a 37th birthday bash shortly after his split from Richie.

Are Scott Disick and Sofia Richie back on? Some fans seem to think so, after the two were spotted out and about in Malibu, California, together on the Fourth of July. In pics obtained by the Daily Mail, Disick, 37, and Richie, 21, can be seen walking side by side on the beach. Kardashian then paid tribute to Disick on Father's Day, and just a few days later, Disick commented "cute shirt" on another one of the Poosh founder's posts.
