Margot Robbie and now an international model – who else is texting Prince Harry?

Margot Robbie was the envy of women around the world when she revealed that she texts Prince Harry. And now the actress has revealed that another stunning woman is in touch with the Prince – her Suicide Squad co-star Cara Delevingne.

The pair were talking about "regular girl stuff" and sharing the most outrageous things they have ever done, when Cara, 23, boasted about drunk texting Prince Harry.

"We just talk about regular girl stuff," Margot told the Daily Star. "And she will then blow me out of the water and tell me she 'drunk texts' Prince Harry. So I'm just like, 'Okay, you win'."

Margot Robbie revealed that Cara Delevingne "drunk texts" Prince Harry

On the other hand, the 26-year-old Focus star likes to keep Harry hanging. "He's pretty quick on text actually," Margot told E! News last week. "Unlike me – I write back four days later, weeks later sometimes."

The actress has previously admitted that she first met the 31-year-old Prince at Suki Waterhouse's housewarming party, while Harry and Cara have "known each other for years".

Margot mistook the red-haired royal for Ed Sheeran. "He got really offended," she told Jimmy Fallon back in March. "He wasn't wearing a crown though, like, I don't know it's a Prince!"

Clearly Harry hasn't held the mix-up against Margot though, and the pair remain in touch.

Both Cara and Margot have been on the promo trail for their new film Suicide Squad. The Londoner plays the Enchantress, a villainess with magical powers, while Margot takes on the role of the Joker's girlfriend Harley Quinn.

Last Wednesday the pair hit the red carpet in Leicester Square to attend the European premiere of their new fantasy film.

Meanwhile, their royal friend Harry has been in Malawi, southern Africa working on wildlife conservation projects. Harry also attended the wedding of Bianca Moore to George McCorquodale – Princess Diana's nephew – in nearby South Africa on Saturday.
