The 37-year-old singer, who married the 33-year-old beauty in Italy in May, is planning to create a dramatic cathedral for the reality TV star's family, so they can host future weddings and baptisms there away from prying eyes, reported Radar online.
"They want somewhere that weddings and baptisms and family funerals can take place for years to come. But Kanye being Kanye, it's going to be ludicrously over the top," a source said.
"He's already set aside USD 5 million to get the work started and plans on doing a series of shows to help fund the construction."
The 'Yeezus' rapper is a huge fan of the famous unfinished cathedral La Sagrada Familia in Barcelona.
"Kanye has visited the church several times, and it takes his breath away every time. He's always wanted something similar for his own family," the source added.
