Adam Lambert's still not entirely sure when his album will be out

Adam Lambert has set a vague 'Mapril' (April or May, port­manteau fans) release date for his delayed second album 'Trespassing'.

Talking to 106.1 Kiss FM, as reported by Idolator, the Queen frontman spoke of the album's delay, saying: "There's some logist­ical things we wanted to get worked out, but there were also some last minute songs we wanted to record."

Lambert went on to describe the album as a mixture of "crazy disco electro funk" and "angstier, darker, atmo­spheric, more emotional songs".

Collaborators on the album include Pharrell Williams, Bruno Mars, Dr Luke and Nile Rogers.
