Lana Del Rey's new album is "so dark it's almost unlistenable."

The "Born to Die" singer has completed work on her second record, Ultra and warned fans it will not be particularly cheerful. According to MTV, she told fans in an online chat, "The record is finished and it's beautiful. And don't worry you will love Ultra - it's so wrong and exquisite. It is absolutely gorgeous - darker then the first - so dark it's almost unlistenable and wrong. But I love it. X."

Her second album may be moody, but the singer's personal life is certainly not, as it was recently revealed she has secretly been engaged to musician Barrie-James O'Neill since last summer. The "Video Games" star and Barrie - previously singer in the folk-rock band Kassidy - first got together in 2011.

Ultraviolence is set to be released this year.
