30 Seconds To Mars superstar Jared Leto has revealed that he recently bumped into The Beatles' Sir Paul McCartney and was so excited to meet him that he asked the 'Hey Jude' icon for some advice about songwriting.

When asked by a reporter for the Rolling Stone if he's working on any new music at the moment, the 'Closer To The Edge' rocker admitted that he is, but might try to get his head down for real now after talking with McCartney about creativity:

"I was in the studio two nights ago working on new ideas. I was talking to Paul McCartney at one of these events during awards season – always great to drop Paul McCartney's name. Don't worry, I'll do Bono next [laughs]. Anyway, I was kind of prodding him for some advice. And he just talked about something I've heard many creative people say before."

Leto added: "He said 'You know what? Just write. Show up every day and write something. And keep writing. Even when you think you don't have something to say, just do it. And wonderful things will happen.' So I'm taking that approach. There are no rules right now. If a song is ready, we could release it. There might be a collaboration or a new song coming. You never know."
