Sophie, who has now returned to the UK after quitting Love Island, was sent a copy of the alleged picture this evening (7 July) but was quick to show she is NOT bothered.
Ignoring the mystery blonde woman, Sophie instead decided to focus on the chest of drawers in the background. Linking Tom into her response, she replied to the post: "Babe, what have I told you about closing your drawers @ThomasJ_powell #untidy."
This is the second time Sophie has been forced to confront the 'woman in thong' Snapchat rumours. It has been claimed that Tom briefly appeared in the video, but he is yet to address the claims himself.
Speaking to Radio Times after her departure, Sophie said: "I'm pretty open minded you know. Tom's allowed to have his fun and I'm sure it was nothing too bad and if he has gone down that route, it's something we'll have to work through."
Last night, Sophie quit Love Island so she could focus on her relationship with Tom, who was dumped from the show last week.
Their relationship hung in the balance, after Sophie shared a kiss with newbie Katie Salmon following his departure, and even Tom admitted he had "no idea what to do".
However, determined to make things work, Sophie has finally managed to FaceTime Tom and admitted it was nice to see his "beautiful face".
Love Island continues at 9pm on ITV2.
