The couple got engaged in December 2013 after two years of dating and one child together, Rex Rayne Wood.
Just weeks ago Fearne shared a loved up snap of her and fiancé Rex celebrating their third anniversary to her Instagram page, showing the pair relaxing by the sea in an unknown location.
In her interview with Red magazine this month, Fearne chatted excitedly about her upcoming nuptials, saying: 'I can't wait to be a wife. It just feels really solid. I want to have the same surname. I want to feel like we've done it properly.'
