The family of a Cardiff school girl who desperately needs a bone marrow transplant, took to Twitter this evening to announce the news they'd been waiting to hear.
"It's the tweet, Hollie has a match. Sincere thanks to all who helped, you know who you are. Love you all."
8-year-old Hollie Clarke has a rare bone marrow failure syndrome.
Her brother wasn't a match, and couldn't donate, so her family launched a campaign to urge people to become donors with the charity Anthony Nolan.
The #pantsonyourhead campaign encouraged people to sign up, and show support by posing for a photograph with their pants on their heads.
A number of famous faces, including Gareth Bale and Sam Warburton backed the campaign, and the family held a donor recruitment drive in Cardiff.
Although the family have been successful, they say they're still not giving up, and will continue the campaign to help other families in the same position.
"Parents in a similar position, keep positive and stay strong. We will be there for you, that's a promise."
The number of people signing up to join the bone marrow donor register in Wales has increased by more than 2500 per cent, compared to this time last year.
The charity behind the register says it's thanks to a family from Cardiff for raising its profile.
The Clark family are looking for a match for eight-year-old Hollie, and to get the message out there they have been asking celebrities to put pants on their heads.
