Since Prince Harry got engaged to American actress and Suits star, <a href="http://vt.co/news/uk/heres-big-royal-tradition-meghan-markle-plans-break-wedding-day/">Meghan Markle</a>, our perceptions about the lives of the British Royal family have been changed somewhat. While we used to see them as the type of people who would only leave the palace to attend a charity event or perhaps watch some horse racing, we now understand that there's a lot more excitement to be had when you're in line for the throne - especially if you're Prince Harry. The 33-year-old royal has been known to rub shoulders with A-list celebrities in the past, and has even been photographed with the likes of Rihanna, David Beckham, and - of course - the Obamas. And, even when he's not hanging out with them, it seems as if he likes to keep in touch with his famous pals via text - as <a href="http://vt.co/entertainment/celebrity/someone-noticed-margot-robbie-celebrity-lookalike-perfect/">Margot Robbie</a> once revealed. "He's pretty quick on text actually," she said a couple of years back. But sending the odd WhatsApp isn't the only way Robbie has kept in contact with the prince. This weekend, the Wolf of Wall Street actress revealed that some of the earliest contact she'd had with Harry was actually via a prank call - and she was spurred on by none other than Cara Delevingne. "Cara knows Harry and while we were filming Suicide Squad she was like, 'Let's prank-call him'," she said. Delevingne then handed over the prince's number, but Robbie was apprehensive about making the call. "I said, 'We can't prank-call ­royalty'," she recalled - but ended up being persuaded by her Suicide Squad co-star. "We did — and he was so cool with it." She then went on to say that "Prince Harry is so nice," and added: "England literally has the coolest royalty in the world." However, the Australian actress did say that the pair weren't super close. "We see each other every so often at a party here or there, but not close friends," she said. In fact, she once attended Suki Waterhouse's housewarming party with Delevingne, and ended up speaking to Harry there without even realizing who he was. "I didn't know it was him for about half an hour talking to him," she previously admitted in an interview with Tina Fey. That same evening, Robbie ended up in a photobooth taking stupid pictures - and Prince Harry can be spotted right at the bottom of the frame sporting some rather attractive neon glasses. Also in the picture was Delevingne, Sienna Miller, Poppy Jamie, and Harry's cousin, Princess Eugenie. Robbie was also pretty sure that she wouldn't be receiving an invite to <a href="http://vt.co/news/uk/heres-get-invite-royal-wedding-according-kensington-palace/">Harry's upcoming nuptials</a>, which are due to take place in May this year. However, a recent statement from Kensington Palace divulged that more than 2,000 non-royals would be offered the opportunity to attend the event, as Harry and Meghan wanted "members of the public to feel part of the celebrations too". Even if she doesn't end up going along, though, I'm sure Robbie will find some other opportunity to hang with the prince in the future; we know he has her number, after all!
