The Irish singer's daughter Mia was jumping on a trampoline when she fell and broke her arm. She was taken to Temple Street Hospital in Dublin, Ireland and doctors decided to operate as the break was particularly bad.
Duffy stayed by his daughter's bedside and was forced to miss a gala at a school in Tipperary on Tuesday (11Jun13) to raise funds for an autism charity.
In a post on Twitter.com, he writes, "Apologies to... the school that I was visiting today, due to personal circumstances I cannot attend today so sorry.
"Mia had a fall off the trampoline and badly broke her arm, she was operated on this morning and is doing fine... I've just spent the last 2 days in Temple Street Hospital with Mia, the nurses the doctors the whole staff were just fantastic."
