Robert Pattinson says he doesn’t talk about his relationship with Kristen Stewart because the secret nature of it gives them both a buzz.

“It keeps things exciting,” the chiselled cutie told the UK edition of OK magazine. “I think most people like to have a secret in their relationship with their girl or boyfriend.”

And letting slip one of his “secrets,” R-Patz revealed he's obsessed with music and loves penning tunes and crooning for his real-life Bella.

Yup, the shaggy-haired hunk makes sweet music outside of the couple’s Vancouver hotel room as well as in. *Swoon*

Not content with just caressing his pretty co-star’s eardrums, the actor has his eye on writing a song for 'The Twilight Saga: Eclipse' soundtrack.

Rob spilled: “I don’t know if it will be possible because of my schedule, but I want to do it. Music is the other side of me, it’s one of the things that completes me and I wouldn’t want to leave it aside for anything in the world."

Sex god, actor, model, now tortured artist – Robert Pattinson, you’re killing us…
