The couple, who live in Martinez' native France with Berry's daughter Nahla, were spotted Wednesday at Los Angeles International Airport, suggesting the ceremony will be a local affair.
E! offered no other details regarding the event, such as exactly where and when it will take place or who might attend.
"I do know it will be very small," she told InStyle magazine last year about the ceremony she was planning.
"I haven't been to many weddings, but I went to one this weekend with 250 guests. I thought, 'Wow -- so this is a wedding, huh?' I've never had that, nor have I wanted that. I wasn't even trying to catch the bouquet!"
Berry and Martinez announced their engagement in March 2012.
