Formula One ace Lewis Hamilton has taken a break from his Grand Prix preparations to bring some cheer to sick children at the Royal Children's Hospital.
Sharnie McDonald, who suffers from Cystic Fibrosis, was in top gear today when she met the British superstar.
The two-year-old is one of his biggest fans.
"It's just incredible to see the smiles and the energy they still have despite the difficulties they are having," Lewis said.
The former world champ took a special interest in three-year-old Emily Tawse, who has cerebral palsy, the same disease as his younger brother, Nick.
Opening up about his personal connection to childhood illness, Lewis said: "My brother's got cerebral palsy and had a very difficult life with that and not being able to talk.
"It was a really difficult time in the family, he's had lots of operations growing up so I spent a lot of time in hospitals when I was younger."
Hamilton is the favourite to win the Grand Prix at Albert Park this weekend.
He also proved to be the favourite visitor of the day at the Royal Children's Hospital.
