- Jamie Gilbert: Riley married Jamie Gilbert in August 2012, having met him at the University of Oxford. They separated in November 2013.
- Pasha Kovalev: Following her separation from Gilbert, she began dating her Strictly Come Dancing partner, Pasha Kovalev, after the show ended in December 2013. Riley has previously clarified that her relationship with Kovalev did not start until “a long time” after her divorce. They married in Las Vegas in June 2019 and have two children.
While her separation from her first husband was sometimes cited in the context of the “Strictly curse” (a media term for relationships ending after appearing on the show), the results do not indicate an affair.
