Gary Barlow says it's ''too early'' for One Direction to consider splitting up.

The 43-year-old singer - who was catapulted to the spotlight as part of boy band Take That - admits groups often have disagreements but insists Harry Styles, Zayn Malik, Louis Tomlinson, Niall Horan and Liam Payne must ''look after one another''.

He told The Sun newspaper: ''There will be rows in a band but you are brothers.

''They might be close sometimes and sometimes not, but it's part of the foundations -- the boys have to take care of one another and look after one another.

''You are having an amazing run and it's brilliant. You can't walk away from that -- why would you?

''Whenever I've met them they seem incredibly adult about the whole thing.

''I think it's brilliant there is such a group representing Britain. If there's any suggestion of trouble, they need to hang on in there. It's way too early to be thinking about splitting up.''

Gary kicked off his 'Since I Saw You Last' tour in Belfast on Saturday night (29.03.14), and reminisced about performing in the city with Take That - which also includes Howard Donald, Jason Orange, Mark Owen and Robbie Williams.

He added: ''We started the 'Beautiful World' tour here with Take That and I'm a bit superstitious. It felt right and it felt like a good place to start. Two hours is a long time for me to be up there by myself, but we'll get there.''
