Hollywood starlet Scarlett Johansson has embarked on another unlikely musical collaboration, this time recording a song with trip hop stalwarts Massive Attack for the soundtrack of Mexican film 'Days of Grace'.

The song in question is titled 'Summertime' and will appear on the film, which follows three different characters during three separate World Cup tournaments. 'Days of Grace' premiered at the Cannes Film Festival earlier this month.

Scarlett last showcased her singing abilities on 'Anywhere I Lay My Head', her album of Tom Waits covers. She had previously released an album with Pete Yorn, entitled 'Break Up', in 2009 and also recently contributed the song 'One Whole Hour' to autism documentary 'One Whole Hour'.
