Westlife are reportedly in talks to embark on a world tour in 2020 when band member Mark Feehily returns from paternity leave.
The boyband's long-awaited comeback has gone down a treat with fans, including two sold-out show's in Dublin's Croke Park, and now they are allegedly drawing up plans to expand on that success.
A source told The Mirror Online: "Westlife's comeback tour has been a remarkable success and interest in their new music has been better than the band ever imagined, so plans are well underway for what comes after the album release in November.
"The boys are in big demand. Mark is going to take a short break when his new baby arrives but then it's all systems go.
"TV execs want the boys for the Christmas schedules and there is already talk of a big world tour in 2020, plans are being drawn up.
"There will also be even more new music with Ed Sheeran. Westlife are popular again. The Twenty Tour sold 700,000 tickets. There is a lot more to come from them, they're in it for the longterm now."
Earlier in the summer, Feehily and his fiancé Cailean O'Neill revealed that they were set to welcome their first child later this year.
The singer announced that he and his partner are set to become fathers to a baby girl during the band's second gig in Croke Park in July.
The four-piece group, Feehily, Nicky Byrne, Kian Egan and Shane Filan, officially reformed last October after an eight-year hiatus.
Their eleventh studio album Spectrum will be released on September 6.
The band recently released the music video for their new single Dynamite which was shot during their Croke Park concerts last month.
