British pop star Tom Fletcher is urging his fans to give blood in a bid to boost "low supplies" in the U.K.
The MCFly singer spent his Sunday morning (30Dec12) donating blood, and uploaded a picture of his bandaged arm to his Twitter.com page to encourage his followers to do the same.
In an accompanying post, he writes, "Just gave blood. Low supplies at this time of year. Go do it if you can and save a life."
