If your girlfriend is a Directioner,what better way to propose to her than by using a 1D song?

That's what Brad did to surprise his girlfriend Emily. you have to see his creative proposal - even Louis Tomlinson's mum thinks so (she shared the video on her Twitter because she loved it so much).

She called all her friends and family, and they did a flash mob to "One Thing." So did she say yes? Well, watch and see.
