The 600-person guest list includes the AC Milan striker's fellow Brazilian national players Ronaldo, Adriano and Cafu, Kaka's spokesman Diogo Kotscho said.

The ceremony takes place at the evangelical Reborn in Christ Church in Sao Paulo. The choir Reborn Praise, with whom Celico usually sings, will perform.

Bride and groom are born-again Christians. The marriage is due to be officiated by Reborn Church founders Estevam and Sonia Hernandes, who are famous in Brazil for their live broadcasts of services.

Kaka, 23, arrives in Brazil on the day of the wedding. After a honeymoon in an undisclosed location, he will rejoin AC Milan on Jan. 2.

He met Celico, a student, in 2002. The romance survived his transfer from Sao Paulo to Italy in 2003 while she was still studying. They will live together in Italy after the wedding, Kotscho said.

Kaka, whose real name is Ricardo Izecson dos Santos Leite, is one of the top players in a Brazilian team that is the favorite to win the World Cup next summer.
