Robert Pattinson has been "writing a lot" of songs recently.

The actor revealed in a Q&A session to promote new movie Cosmopolis that he is thinking about returning to his musical roots once the Twilight franchise finishes later this year.

Before he found worldwide fame with his roles in Harry Potter and the hugely successful vampire saga, the star had dabbled with a career as a musician.

"[I have] been writing a lot of stuff recently. With Twilight coming to a close, I feel more comfortable doing that," he told MTV. "I miss it. I might do some stuff soon."

Robert, who plays the guitar and piano, has previously said that music was his Plan B if his Hollywood career didn't work out.

The 26-year-old even performed two songs on the Twilight soundtrack, Never Think, which he co-wrote, and Let Me Sign.

"I've never really recorded anything - I just played in pubs and stuff," he said previously. "Music is my back-up plan if acting fails."
