Lily Allen records duet with Robbie Williams to mark music comeback

Lily Allen, who announced her comeback to music last week, has reportedly roped in Robbie Williams for a duet.

The 28-year-old 'Smile' singer, who retired from music in 2009, has recorded a duet 'Dream A little Dream' with the 39-year old former member of 'Take That', the Daily Express reported.

Allen admitted that she was a bit nervous while the song was being recorded, but is happy with the outcome and believes that they did justice to the classic song.
