Last Sunday Harlow became the latest VIP to be invited to wave the flag at the end of a GP, but did so because she was given the wrong instruction from an official.
Brawn used his regular post-race debrief to say sorry for the outcry this triggered, with a lot of criticism directed to Harlow on social media.
"Supermodel Winnie Harlow was an innocent victim at the end of the race," said Brawn.
"She was asked to wave the chequered flag, but was told to do so after 69 of the 70 laps had been completed.
"I was sad to see her so heavily criticised when, as race director Charlie Whiting explained, it was all down to a misunderstanding between two officials.
