Jennifer Aniston and Justin Theroux plan to marry in Kenya in December.
The couple have planned a nine-night private safari in the African country for the first week of December where they will have an informal blessing although they will also have a formal ceremony in Los Angeles on their return.
A source told the Daily Mirror newspaper: "Both Jen and Justin want a private and intimate wedding, and they love the idea of eloping and marrying abroad. Kenya will be an amazingly romantic break and the plan is to have some kind of informal blessing while out there. They may well undergo something more formal in L.A. immediately afterwards."
However, Jennifer's reconciliation with her mother Nancy following years of feuding could cause problems as Nancy wants to attend the wedding but is not well enough to travel after having a stroke last year.
The source added: "Now that Nancy and Jen have fixed their relationship, Nancy desperately wants to see her daughter get married.
"Sadly she had a major stroke last year and can’t travel if they do elope. Basically Jen has to choose between her mum and her dream wedding."
