Stefani 'annoyed' by Rossdale duet

Gwen Stefani is annoyed with her husband Gavin Rossdale for including a duet they recorded for fun on his new album.

The former No Doubt singer offered to lend her vocals to Rossdale's track 'Some Days', while he was working on his latest album, 'Wanderlust', but the new mum never expected the song to make the final cut.
