The four mini-films called 'the four dreams of miss x' will feature Moss as a mysterious lady in various saucy scenes, although viewers will not know it is the supermodel until the final spot.
It is understood that the 32-year-old will be shown walking down the street in racy knickers, draped over a chair wearing next to nothing and writhing naked on the floor.
Agent Provocateur's owner, Vivienne Westwood's son Joe Corre, told the Daily Mirror: "Watch out for something in September that is huge – but top secret for now."
Moss appears to have emerged from recent troubles when she was cleared of charges relating to her being pictured snorting cocaine at a London recording studio with former boyfriend Pete Doherty, and has gone from strength to strength.
The supermodel has struck a number of lucrative deals, including her return as the face of Calvin Klein for around £500,000 in April.
In addition, she has secured a £1.2m Virgin tie-up and a £1m Stella McCartney contract, while appearing in a new campaign for Rimmel London.
This new deal is also understood to be worth around £500,000 and Moss is now said to be worth around £30m.
Kylie Minougue featured in a previous viral campaign for the underwear firm riding a bucking broncho to the accompaniment of The Hives' 'Main Offender' track.
