Prince Harry and actress Meghan Markle caught goofing around after the cameras stopped rolling, as lipreader reveals what they were saying

A footage from Prince Harry and Meghan Markle's engagement interview that wasn't shown to viewers last night has now emerged and in it, the newly engaged couple are seen goofing around immediately after their interview stopped airing.

In the footage, Harry and Meghan are shown laughing, joking and chatting with each other, interviewer Mishal Husain, and other people off screen but unfortunately the microphones were switched off so what they were saying could not be heard. However, lip readers have now revealed that the couple's discussion was about the talkative Suits' star not letting her royal husband-to-be get a word in during the interview.

Expert lipreader Tina Lannin, whose company 121 Captions specialises in forensic lipreading for the police and CPS, has told MailOnline that Harry is ribbing his fiancee for interrupting him while he was speaking during the interview.

While he is believed to be describing their safari in Botswana last year Meghan cuts across the prince and says: "It was 5 days, yeah".

Showing their relaxed relationship Harry then tells her: "She wants me to say something" and saying "Goddammit" while slapping his leg in fake outrage. After apologising, Meghan says jokingly: "Do it again!".

This afternoon the couple are expected to reveal the date and venue of their wedding which will hold next year.
