Britney Spears' father is set to earn over $1 million from her world tour.

The 'Piece of Me' hitmaker - who has been under the conservatorship of her dad Jamie since her much-publicised breakdown more then three years ago - also employs her parent as tour manager on her current 'Femme Fatale' global run of shows and while the position is unpaid, he is set to be rewarded for his hard work.

The singer's manager Larry Rudolph is set to earn 10 per cent of the gross profit from the tour, but wants to give two per cent of his cut to Jamie as a thank you gesture for the duties he has carried out since taking on the position in February.

According to documents obtained by TMZ.com, Jamie was instrumental in negotiating a deal with tour promoters Live Nation for Britney and has also been responsible in handling finances, managing the singer's security, arranged her personal schedule and monitored her arrivals and departures, and also undertook between 200 and 400 calls and other communications a day on behalf of his daughter.

Larry's voluntary pay offer to Jamie has to be approved by a court, but this is said to just be a formality.
