The two Irish singers were on Lorraine to talk about their new boyband Boyzlife.
Brian was part of Westlife and Keith was in Boyzone, so the duo decided to team together to create their new supergroup.
However, things got a bit cheeky between Brian and Lorraine when they started talking about golf.
The TV presenter couldn’t get over the boys’ obsession with the sport and said: “Do you not get fed up of it, cross with it?
“You go out and do exactly the same thing, the exactly the same course, the exactly the same clubs, you’re rubbish and then the next day you’ll be good.”
To which Brian replied with: “Lorraine, is that not what you’ve been doing for the last 25 years?”
The 57 year old was left shocked at the comment and then burst out laughing.
“That’s very true,” she quickly added.
However, the banter didn’t stop there and Keith decided to say: “Where’s your social life gone? Do you have one?”
To which she replied with: “No.
“Cinderella as you know, always got to leave early!”
While Brian added: “Get yourself some golf clubs and when you’ve finished yapping here in the morning, go out onto that golf course.
“It will change your life forever.”
Viewers were left in hysterics over the Boyzlife members antics and took to Twitter to share their thoughts.
One person said: “You need to get Boyzlife as guest presenters #Lorraine”.
A second user put: “#Lorraine, how funny were they, should have their own show!”.
While a third account added: “Keith and Brian should have their own TV chat show they’re lots of fun with plenty of cheeky chat #Boyzlife #Lorraine x”.
Lorraine continues on weekdays at 8:30am on ITV.
