Lady GaGa becomes Iron Maiden roadie

Lady GaGa is reportedly such a huge fan of British heavy metal band Iron Maiden that she has been helping the band backstage during their Florida tour stop.

The 'Judas' star has appointed herself an unofficial roadie for a couple of dates of the band's The Final Frontier World Tour, helping out on the tour bus with chores such as ironing and serving drinks.

"It's a side to GaGa we've never seen. She is a massive Iron Maiden fan and was willing to be at their beck and call, just to hang out with her idols," a source told The Mirror.

"She was humming along to their hit 'The Number of the Beast' while carrying out her chores. And after all her hard work backstage she was rewarded with some drinking games."

GaGa is said to be so taken with the rockers' leathers that they have become a "major inspiration" to how she is planning to dress for her upcoming tour dates.

"GaGa is always thinking of unique ways to take her sound to the next level, so a collaboration with Iron Maiden would be her dream," the source added.

The 25-year-old singer recently revealed that she has worked with AC/DC producer Robert John Lange for new album track 'You and I', also enlisting Queen guitarist Brian May to work on the song.

Lady GaGa is expected to premiere the video for her new single 'Judas' over the Easter period.
