Ross claimed she had confused him with her clue that she had been in the ITV soap Emmerdale.

Jenkins revealed: “I was in Emmerdale. I had a small cameo where I sang at the village fete.”

Judge Rita Ora correctly guessed Octopus’ identity after she slipped in some operatic notes into her performances.

Ora said: “I knew as soon as heard that.”

Jenkins said of the show: “My normal career can be quite static so singing songs I wouldn’t normally sing has been so much fun.”

The Welsh singer - who has had 13 Number One albums - had tried to throw the judges off the scent by speaking with an American accent.

She said: “I was trying to fool you. My husband is American and I thought my Welsh accent was a give away.”

Jenkins has been married to American artist and film director Andrew Levitas since 2014. They have a four-year-old daughter Aaliyah and a 22-month-old son Xander.
