Elle and Bonnie Ann told BBC News NI that they developed an “Irish alliance” on the show, which features 10 other drag queens from across the UK.
They found a third ally for their sisterhood in Welsh drag queen Catrin Feelings.
“We were the Celtic Sisters and that was established from the jump,” said Elle.
“The Celts are coming to take over,” joked Bonnie Ann.
Bonnie Ann Clyde has been performing for almost 11 years across the island of Ireland, in Gran Canaria, and now in Manchester.
Although she said there are “no abject rules” on who can and cannot compete, when she moved to Manchester it felt like the chance to represent the Republic of Ireland on the show was closer.
“I think everything you do as a drag queen, in the world where Drag Race exists, is with sense of could this get me on Drag Race?” she explained.
Being the first person to represent the Republic of Ireland is “a lot of pressure but a lot of fun”, she added.
