Lana Del Rey is struggling to find enough inspiration to fill a third album.

The Young & Beautiful hitmaker's fans were concerned she might be retiring from music when she referred to her short film Tropico as her farewell project in August (13) in a post.

Despite fans' questions, Del Rey has never explained the comment and she has now admitted a follow up to 2012's Born To Die is still a long way off.

The singer tells Nylon magazine, "When people ask me about it, I just have to be honest - I really don't know... I don't want to say, 'Yeah, definitely - the next one's better than this one', because I don't really hear a next one. My muse is very fickle. She only comes to me sometimes, which is annoying."
