Justin Bieber had a busy day - he then went to delight sick kids as
part of a special meet-and-greet set up by organisers at the
Make-A-Wish Foundation charity.
Taking to his Twitter.com page after the event, he wrote,
"MakeAWish thanks for having me. best part of the job. Everyone
follow them as they r (sic) an inspiration."
The singer also reportedly managed to fit in a doctor's appointment
and submit to a DNA test on Friday to disprove allegations he
fathered a child with California woman Mariah Yeater.
