Watch: Brian McFadden and Shayne Ward take on Celine Dion's All By Myself

Brian McFadden and Shayne Ward have got in touch with their feminine side in a hilarious video posted by the Westlife star.

Brian and X Factor star Shayne can be seen serenading each other, belting out Celine Dion’s All By Myself.

The musicians are currently working together on West End show War Of The Worlds, and decided to mess around during a break from production.

In the video that will no doubt give them massive street cred in the music business, the pop stars joke around and give fans a sneak peak of what they get up to backstage.

Brian, 34, shared the video on his Twitter account, writing: ‘Here’s me and Shayne Ward duet! Out for Xmas!’

The video comes only  a week after Brian’s invoice for his TV3 Toy Show hosting gig was accidentally emailed to the entire TV3 news room.
