The Maroon 5 singer got engaged to the Namibian model in July and the couple have been contemplating where to hold their nuptials.
The lovebirds have been deliberating whether to hold the big day in Los Angeles - where they live - or Behati's native Namibia, because it would mean a lot to her parents to have the wedding in the African compromise.
Adam has now come up with the idea to have two ceremonies so they are no travel difficulties for their families and friends.
A source told the new issue of Life & Style Weekly magazine: ''He went back and forth about having the wedding in Behati's native Namibia or in Los Angeles, where they live. Behati's parents would love for the wedding to be in Africa, but they understand that it is a major trek for all of their friends.''
Adam, 34, and Behati, 24, want to have an intimate ceremony in Namibia and a bigger celebration in Los Angeles which can include their friends and American-based family.
'The Voice' judge Adam proposed to Behati - who he has been in a relationship with since May 2012 - at a romantic location in Los Angeles in July.
