Quick, somebody tell Robbie that her facial expression is the last thing people look at, when she is on a red carpet!
Or elsewhere for that matter.
This Australian-born actress says she is not very good at making those duck faces, while being photographed and filmed live, on some kind of a event, or TV show.
The 27-year-old became famous appearing in The Wolf of Wall Street (2013), alongside Leonardo DiCaprio.
She was also big in the Suicide Squad (2016), so big in fact that she will reprise her role of Harley Quinn in at least four more upcoming movies.
In 2018, we will have a chance to watch her in three big screen hits: Mary Queen of Scots (2018), Dreamland (2018) and Terminal (2018).
Robbie has won many awards, and she has been nominated for even more prizes. Currently, she is waiting for the biggest movie event of the year - the Academy Awards show - because she was nominated for Best Leading Actress award, for I, Tonya (2017).
