They've shot to fame with hordes of fans lavishing them with love and attention.
But that's not going to the One Direction boys' heads. The singers took time out of their hectic tour schedule to meet some special fans ahead of their latest gig in London.
The five-piece were getting set to take to the stage for their Hammersmith Apollo show on Sunday. But before they headed out in front of the screaming audience, the boys spent some time with some ill children from the Rays of Sunshine charity.
The band are all ambassadors of the organisation, which grants wishes for seriously ill children in the UK aged 3-18. And Harry Styles, Liam Payne, Niall Horan, Zayn Malik and Louis Tomlinson made the wishes come true for two special girls ahead of their gig.
The boys posed with 11-year-old Tilly and blonde Rebecca, 15, and chatted to the girls before taking to the mics.
Tilly, who is a big fan of The X Factor stars, is suffering from Spinal Muscular Atrophy.
But despite being wheelchair-bound, she rides ponies, sails, ice-skates and goes to ballet classes every week, in her own special dancing frame.
And she received an extra special treat as she was given signed goods by the stars and got to cuddle up to Louis and Zayn. She smiled from ear-to-ear as snaps were taken of her alongside all of the bandmembers. But she wasn't the only one to meet the guys before the London show - Rebecca, who suffers from cystic fibrosis, landed the special experience thanks to her mum.
The teenager's mother applied for the wish because she knew if would lift her spirits and give her something 'positive to focus on'. And it certainly seemed to have done the trick as she stood next to the stars for a series of pictures.
And following the fan meeting session, the boys couldn't wait to perform at the gig in London.
Niall wrote on Twitter following their gig in Cardiff, Wales on Saturday: 'Sham wea cardiff! Sick show tonight! loved it! London again tomorrow! Lets goo! #bedtime'
