The couple have been together for 10 years, after they met at a Gucci shop in Madrid where Rodríguez was working. He was playing at the Spanish club Real Madrid at the time.
They announced their engagement on 11 August last year.
At the time, Rodríguez posted a picture of a large ring, writing "Yes I do. In this and in all my lives" in her native Spanish.
