A romantic surprised the love of his life by secretly travelling to New York to propose to her under the world's largest Christmas tree. Rikki Horn, 27, planned a transatlantic trip to coincide with his partner Melanie Walker's pre-planned girls' shopping holiday to New York City. The father-of-one secretly booked a separate trip by himself to spend just one night in the city to ask the big question. He only told his partner's friend Cheryl Brown of his plans and plotted with her using Snapchat so that Melanie was kept in the dark.
