Feehily says his pneumonia is "under control" but that he needs to focus on recovery after already missing some of the scheduled gigs.

After withdrawing from the tour on Friday and Saturday, Feehily said: "I really was gutted to miss the weekend shows in Newcastle but I really started to feel quite unwell on Friday and the doctors confirmed that it's a bout of pneumonia."

The singer continued: "I know it's scary when you first hear the word 'Pneumonia' but thankfully I got to the doctor and hospital very quickly and got on the antibiotics as soon as possible, so everything is currently under control."

"I have been informed that the quickest way to recovery is to rest and continue the antibiotics. I'm feeling a bit better everyday."

Feehily reassured his fans saying: "The nurses and doctors are taking amazing care of me so it should all be over in no time. This does however mean missing more gigs which is horrible but I'll be back on stage as soon as I get the all clear."

The other band members will continue the Westlife Wild Dream tour, Feehily said in the post.

"Nicky, Shane and Kian will continue to fly the Westlife flag high for all of us. Please scream even louder than usual for those three legends in my absence."

What is pneumonia?

According to the NHS website, pneumonia is usually caused by bacteria or a virus and leads to inflammation of the lung tissue. Some of the symptoms include:

• a cough
• difficulty breathing
• rapid heartbeat
• high temperature
• feeling generally unwell
• sweating and shivering
• loss of appetite
• chest pain - which gets worse when breathing or coughing

Westlife split up in 2012, but reunited in 2018 without Brian Mcfadden, who left the group in 2004.

In July 2022 they kicked off their Wild Dreams tour and sold out Wembley Stadium.
