Duffy has released her first single in five years.
The 'Mercy' singer - who appears in Tom Hardy's new movie 'Legend' - sent fans into meltdown over the weekend after she quietly dropped her new track 'Whole Lot Of Love' via her Facebook account.
The song, which marks the blonde beauty's first single since 'Well Well Well' in 2010, also features as one of the three soundtracks in the new crime thriller, 'Legend.'
The Welsh star - whose full name is Aimee Ann Duffy - took to her social networking sites last week to tease fans about a possible new single, before dropping it two days later.
Duffy shot into the music scene in 2008 with her hit singles 'Rockferry' and 'Mercy', with the latter climbing into the charts worldwide.
In 2010, she released her second album 'Endlessly' but after it received criticism, she decided to take an extended hiatus.
Over the past four years, the star has turned her attention to her acting career but is seemingly determined to incorporate her love of music back into her life.
'Legend', which sees the singer portray Timi Yuro, is out in cinemas now.
