The star-studded contest will take place in the early hours of Thursday morning, live on Sky Sports, as Orlando City's Kaka is set to play against some of his former Real team-mates.
"To take on Madrid is a very good experience," the former Brazil international told US Spanish-language newspaper Hoy. "When I was there I played once against Milan, and now with the All-Stars team I will play against Real Madrid.
"It is something very emotional. To take on staff at the club and ex-teammates of Real Madrid will be a very different experience for me."
Kaka is part of an MLS All-Star side which includes team captain Bastian Schweinsteiger, Sebastian Giovinco and David Villa, who will face the Galacticos starring Gareth Bale and Karim Benzema.
