A sharp-eyed New Zealand journalist sparked a racism row at the Australian Open involving beaten finalist Serena Williams.
Media commentator Russell Brown tweeted video of a Williams "fan" in the stands who had blacked her face.
Dressed in shocking yellow to mimic Williams' famous Aussie Open attire, the women and a friend - who had black patches on her face - held up a sign 'Keep Calm and be Serena'.
The semifinal incident in Melbourne and Brown's tweet were picked up by major news organisations including England's Daily Mail and Independent.
