He took an 18 month break from performing after Westlife broke up, and now Markus (née Mark) Feehily is back with a bang - and a catchy new song!
Love Is A Drug is the lead single from Mark's forthcoming debut album, expected later this year.
And what can we expect from the hotly-anticipated new album?
"Songs that I've written about experiences that I've had - soulful, autobiographical pop music," Mark says. He's delighted we've chosen it as our Song of the Week:
Ah Jaaaaaysus :) That's GREAT! RT @IanDempsey:Song of the Week is 'Love Is The Drug' by @MarkusFeehily. What a voice! http://t.co/eApFUza4JC
