Liam Payne missed his granddad's funeral because of One Direction's current Take Me Home world tour.

The 20-year-old boy band singer is devastated following the loss of his grandfather but has been grateful for the huge amount of support he has received from fans who took to twitter to show they were thinking of him, leading to the hashtags ''#RIPGrandpaPayne'' and ''#StayStrongLiam'' trending on the social networking site.

The star later wrote on his own page to thank his fans for their kind words, writing: ''Thanks for everyone's support at this hard time obviously this has been a tough few weeks for me I've never been through anything like this.''

Liam dedicated the track 'More Than This' to his grandfather whilst on stage in Australia, as he was not able to be with his family during this difficult time.

One Direction - which includes Niall Horan, Zayn Malik, Harry Styles and Louis Tomlinson - kicked off the Australian leg of their 'Take Me Home' world tour in September.

They took to the stage last night (02.10.13) at the country's culture capital Melbourne performing at the Rod Laver Arena and are set to do so again tonight (03.10.13).
