Westlife’s Nicky Byrne sparked friendly rivalry with Boyzone’s Ronan Keating as he spotted a coffee shop putting the Irish bands head to head.

The World of Our Own star was enjoying a bank holiday trip when he came across two tip jars side by side on a cafe counter – one labelled Boyzone and the other with Westlife.

A note said: “Choose wisely. Vote below.”

Documenting the funny find on Instagram, the Dublin-born singer turned TV and radio presenter told his fans: “Interesting ‘tip jar’ in @coffeeworkseire today!”

He then tagged Boyzone’s frontman and fellow Dubliner Keating, 45, in the post. The RTE star, 43, also filmed himself putting some coins into the Westlife jar, adding: “I had to support my own.” Ronan commented: “Ahhh you’ve changed. I remember when BZ was your number one.”

His former Boyzone bandmate Keith Duffy also jumped in on the teasing, and wrote: “Ah giz a few bob Nicky”.

Irish football legend Robbie Keane was amongst others to weigh in on messing.

He teased Nicky saying: “Ronan would have given a bigger tip, just saying.”

Nicky replied: “Be careful they had Messi v Ronaldo yesterday, you could find yourself up against Shearer!”

Meanwhile, fans joined in on the debate, with many left struggling to make a choice between the bands.

One wrote: “I can’t vote, I love you both.”

Another said: “Boyzone was my first ever concert, but Westlife all the way.”
