Brian McFadden took to Twitter to call on Irish lawmakers to legalise same-sex marriage in his native country and grant "equal rights for all".

The former Westlife boyband popstar has shown his support behind a campaign to urge politicians to alter the majority Catholic country's strict laws and to reflect modern attitudes towards sexual orientation.

He tweeted: "Legalize gay marriage. Come on Ireland. Let's join the 21st century!!!!!! Equal rights for all!!!!!!!!!!"

McFadden's friend, Westlife singer Mark Feehily, came out in 2005 and announced his engagement to long-term boyfriend Kevin McDaid last year.
