Adele still hasn't chosen a producer for her new album.

The 26-year-old singer - who initially hinted the follow up to her hit 2011 record '21' would be released in 2014 - is reportedly still undecided over who to team up with on her latest offering and may be forced to push back the album's release even more.

Producer Emile Haynie - who met up with Adele in February to discuss the possibility of working together on the record - said: ''Adele was awesome, but I don't know if we'll be working together.

''We got along well as friends when we met in February and I hope we can cut some songs, but Adele is taking her time.

''I'd push for it to happen, but we'll have to wait and see.''

Emile, 34 - who has worked with Kanye West and Bruno Mars in the past - also admitted he sought help from pal Lana Del Rey when it came to releasing a record of his own.

The producer - whose album 'We Fall' features the 29-year-old singer as well as Florence Welch and The XX - penned the record following a break up and Lana was quick to offer him advice on how to turn his heartbreak into a song.

He told the Daily Star newspaper: ''Lana came by a couple of days after the breakup when it was still hellish.

''She gave me loads of advice and the next thing you know we're cutting the song.''
