Paltrow credits Guinness with calming her ahead of live gig

Gwyneth Paltrow got performance tips from Beyonce, and a little help from Guinness, ahead of her live singing debut.

The US actress admitted she "couldn't sleep" for nerves ahead of her appearance at the 44th Annual Country Music Awards (CMAs) in Tennessee on Wednesday - but studying her A-list friends helped build her confidence ahead of performing the title track from her new film 'Country Strong'.
