Margot Robbie is one of Australia's - and well, the world's most gorj women – so when she give beauty advice we'll listen.
The Suicide Squad star has revealed that she uses nipple cream to keep her lips looking super plump.
“I have a conspiracy theory that lip balms actually have additives in them to dry your lips out so you keep buying them. But because Bepanthen is just a cream for dry skin, it works.”
Good news for fans - it's only valued at $8.
