and we have chosen the traditional format of mixed-sex couples". The press has reported on the issue on numerous occasions when gay celebrities have appeared on the show, including Will Young, Susan Calman, Robert Rinder, Richard Coles and Ranj Singh. Strictly Come Dancing judges Shirley Ballas and Craig Revel Horwood have both expressed their support for introducing same-sex couples. Same-sex partnerships have been featured on several international versions of the show, including Austria (2011), Italy (2015), Australia (2019) and Germany (2019). On 3 November 2019, Johannes Radebe and fellow professional Graziano Di Prima performed together to Emeli Sande's "Shine" on the Sunday results episode, the show's first individual same-sex dance. On 2 September 2020, it was announced that boxer Nicola Adams would feature in the show's first same-sex couple for its eighteenth series. She was partnered with professional dancer Katya Jones. In 2021, it was announced that John Whaite would feature in the first all-male same-sex couple with Johannes Radebe for the nineteenth series. The United States version of the show would also have a same-sex couple that same year, with JoJo Siwa & Jenna Johnson. Series 20 also included same-sex partnerships with Richie Anderson and Giovanni Pernice in an all-male partnership and Jayde Adams and Karen Hauer in an all-female partnership. Strictly curse The so-called "Strictly curse" has been blamed for the number of affairs and relationship break-ups that have occurred during or soon after taking part in the show. The first such incident was the suggested affair between dancer Brendan Cole and newsreader Natasha Kaplinsky during the initial series: they both denied the affair, but the surrounding controversy resulted in the ending of both their long-term relationships. COVID vaccinations In September 2021, The Sun reported that at least three unnamed professional dancers had allegedly refused to get a COVID vaccine. A report in The Times claimed The Mail on Sunday had attempted to name some of the unvaccinated dancers but was met with "strong pushback" from their lawyers. Amy Dowden, Oti Mabuse, and Giovanni Pernice have all publicly confirmed that they are vaccinated. Judges Shirley Ballas, Motsi Mabuse, and Craig Revel Horwood are all vaccinated. Ratings An example of Strictly Come Dancings popularity is that, after episodes, electricity use in the United Kingdom rises significantly as viewers who have waited for the show to end begin boiling water for tea, a phenomenon known as TV pick-up.
