Ms. Robbie, 30, is known for her leading roles in blockbuster films such as The Wolf of Wall Street and Suicide Squad. In an interview with New! magazine, the Australian actress said she had met Prince Harry, 35, at parties in the past.
She added that she had yet to meet Meghan Markle, 39, but said “it would be cool to go out. ”
The Once Upon a Time in Hollywood star also gave advice to Harry and Meghan, who moved to Los Angeles earlier this year after deciding to step down as senior members of the royal family.
She advised the Sussexes to ‘give time’, adding that she herself had moved to another country twice.
Ms. Robbie described the experience as “not easy” but said “Los Angeles has a lot to offer”.
Harry and Meghan no longer live in Los Angeles because, according to reports, the couple moved to the nearby coastal town of Santa Barbara after buying a house this summer.

If Harry and Meghan visit Ms Robbie’s house, it won’t be their first contact with the celebrity.
When the couple first moved to Los Angeles this year, they stayed in a large house owned by American actor Tyler Perry.
They are also said to be close to the host of the American television show Oprah Winfrey, who said in January that she “1000%” supported their decision to step down from royal duties.
Mrs. Winfrey would also be a close neighbor of the Duke and Duchess in their new home in Santa Barbara.
Meghan Markle also met former First Lady of the United States Michelle Obama.
The two met after Markle attended a speech the former First Lady was hosting in London.
Markle also interviewed Michelle Obama, wife of former US President Barack Obama, for her guest edition of British Fashion, according to Hello Magazine.
Recently, Markle spoke out to encourage American citizens to vote in the upcoming presidential elections due in November.
Prince Harry, however, should take a step back, as the royal family is traditionally supposed to be politically neutral.
