Big brother contestant soma drops new single one plus one

I'm not aware of any information about a Big Brother contestant named Soma releasing a new single called "One Plus One". It's possible that you may be thinking of a different celebrity or artist.

Soma Sarwar is a contestant from Season 18 of Big Brother, but I couldn't find any information about her releasing a single or music career. If you could provide more context or clarify who Soma is and what kind of music she makes, I'd be happy to try and help you find more information.
