Nathan Sykes' girlfriend to pen song about him

Singer Nathan Sykes' girlfriend Ariana Grande is writing a song on him and their relationship.

The couple has been dating from some time and Grande says she has learned a lot of things from her relationship with The Wanted band member.

"You best believe I'm going to be writing about him! I think that's beautiful and it's something which should be expressed," femalefirst.co.uk. quoted Grande as saying.

"I'm always going to be as honest I want to be. Music is the greatest form of self-expression. I'm the happiest I've ever been and I'm learning a lot of lessons from this relationship," she added.
