Pop superstar Harry Styles has thanked fans after they donated more than $10,000 (£6,250) to a children's charity to mark his 20th birthday. The One Direction singer left his teens behind as he celebrated the milestone on Saturday (01Feb14), with reports suggesting his rumoured girlfriend Kendall Jenner threw a lavish bash at her father Bruce Jenner's Malibu home. Styles took to Twitter.com in the midst of his special day to reach out to his devotees who had handed over money to Believe in Magic, a U.K. charity which works with terminally ill children. He tweeted, "Just saw donations to believeinmagicx for my birthday. Thank you.. You're all very very kind and nice." Styles later added, "Just sitting around being 20." More than 360 fans had made donations to the fundraising page of Justgiving.com as WENN went to press.
