The former United States marine and Paralympic hopeful let the news slip while being quizzed by reporters about attending Harry's wedding. When pushed further, she said, "I am pleading the fifth", which, it's a little late for that Ennis!
According to The Express, Kirstie nodded in response to a question by reporters about going to the prince's "upcoming wedding" and then said: "I don't think I'm anxious about the wedding. I'm anxious about the after party".

According to Daily Star, former United States marine Kirstie Ennis, who has been friends with Harry for five years after meeting him at a Walking With the Wounded charity event, confirmed she was expecting a royal wedding between the pair.
Ennis was injured in a helicopter crash in Afghanistan in 2012 that left her with brain and spine damage, a smashed jaw, arms and legs.
Reports swirling around suggest that Harry will pop the question before his 33rd birthday in September.
