The 35-year-old 'Maroon 5' frontman is apparently planning to get married to Prinsloo on July 19 in an 'intimate' celebration, reported Contactmusic.
A rehearsal dinner will take place on July 18, and the couple, who started dating in 2012, will exchange vows the following day.
A gathering the day after the wedding to allow guests time to say goodbye to the newlyweds is also apparently planned.
Behati, 25, recently said she has already got her wedding gown.
"It's bohemian, very beachy. Very me," she had said.
