Jedward’s tour manager has denied that the Irish twins are gay.

Liam McKenna told New magazine that despite speculation, the excitable duo like girls but won’t discuss sex on Celebrity Big Brother in case their grandmother finds out.

According to Digital Spy, he said: “They are really shy. I’m sure they do fancy girls but don’t like talking about sex as they’re probably aware that their granny is watching.”

Mr McKenna added that the twins, otherwise known as John and Edward Grimes, idolise evangelical Christian popstars the Jonas Brothers.

He said: “The Jonas Brothers are their idols and they said they didn’t want sex before marriage. I think the boys live their life by these guys.”

The pair are currently appearing on Channel 5’s Celebrity Big Brother. Fellow contestant Darryn Lyons interrogated them about their sexuality but the twins said that although they haven’t had girlfriends, they are not gay.

Jedward finished sixth on 2009’s X Factor. This year, they won eighth place for Ireland at the Eurovision Song Contest.
