Suman was once rumored to be dating Johnny Thackway, a top British model and fitness instructor. However, there is no further information about their relationship, and Suman's social media pages are mostly filled with photos of her costars and her acting adventures.
In December 2018, though, Suman helped Thackway raise money for a good cause by tweeting about his mission to help people experiencing homelessness. "Johnny Thackway is doing a 12hr workout to help raise money for the homeless this X-mas," she wrote alongside a photo of him. "To donate, visit @johnny_thackway insta page and to see his progress. Support and shares would be grately appreciated. Link to just giving page is on his bio. ❤ #helpthehomeless."
