The pregnant Oscar winner, her fiance and her daughter Nahla were photographed arriving at Los Angeles International Airport to board a flight on Wednesday (10Jul13), and sources tell both People.com and Eonline.com that the nuptials are imminent.
The couple became engaged in March, 2012, and will welcome its first child together later this year (13).
If the rumours are true, it will be Berry's third trip down the aisle; she had previously sworn off marriage after failed unions to baseball player David Justice and singer Eric Benet. Martinez, who previously dated Australian pop superstar Kylie Minogue, has never been married.
The ceremony is expected to be an intimate one - discussing her plans last year (12), the actress said, "I do know it will be very small. 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."
Nahla, five, is Berry's child with her model ex, Gabriel Aubry.
