When Margot Robbie sat down with MTV Australia to chat about her latest film, Peter Rabbit, she was in for quite the unexpected prank. While settling in alongside her costar Elizabeth Debicki, Margot's younger (very attractive, might I add) brother, Cameron, nonchalantly crashed the party, much to Margot's surprise. The Australian actress was visibly shocked by his arrival, as she exclaimed, "Oh my god! What are you doing? Shut up!" while Cameron jokingly added, "Excuse me, this is a professional situation; can you just calm down?"
Once Margot composed herself, Cameron rattled off a few interview questions about Peter Rabbit, including asking about his sister's "dim-witted" and "airy" character, Flopsy. Watch the adorable siblings poke fun at each other in the video above, and then relive that time Cameron trolled Margot after the Oscars.
