Queen of Pop Madonna says working alongside her children on her recent world tour was an "amazing" experience.

The international superstar stepped out at the premiere of her new documentary 'Madonna: The MDNA Tour' this week which chronicles life on the road with her sell-out string of shows.

Madonna's daughter Lourdes, 16, helped out in the wardrobe department and 12-year-old son Rocco danced with the star on stage.

The songstress gushed to Access Hollywood: ”[It was] great and amazing to work with both of them. I think working and earning a living is always a good experience for a child."

Madonna thinks her kids took a lot away from the experience too.

She continued: ”[They got to] travel the world and had to deal with all the ups and downs of doing shows outdoors. Rain, extreme heat, torrential downpours, hail, freezing cold,” she explained. “So pushing through any kind of limitations and having the attitude of the show must go on, no matter what [was] good training."

A host of stars joined Madonna to celebrate her new documentary including Adam Lambert, Zachary Quinto and Kelly Osbourne.

The superstar's boyfriend Brahim Zaibat also attended and posted a photo of him and Rocco shirtless afterwards.

Writing on Instagram he exclaimed: “And of the night with @rrsoap we went zodd shout out to my #mdna familly great job everyone!! (sic)."
