Los Angeles:
The 43-year-old actress got engaged to Justin Theroux on Friday (10.08.12) and although Nancy Dow wasn't asked to attend her nuptials to Brad Pitt, Justin has convinced Jennifer to put the past behind her.
A source told RadarOnline.com: "Nancy and Jennifer have had their ups and downs, but they're going to let bygones be bygones and she will be invited to her daughter's wedding ceremony.
"She was told of the invitation by her son, John Melick [Jennifer's half-brother], which she was obviously delighted with.
"Sadly, the initial fallout between Nancy and Jennifer in 1999 meant that she wasn't on the guest list for the 2000 wedding to Brad - something that always haunted her.
"But the pair have healed their differences and, with the help of Justin, Nancy will get an invite this time around.
"Justin comes from a tight-knit family, who he is very close to. He preaches family values to Jennifer and he said to her he'd love a private, low-key ceremony with all their family members present.
"She agreed, said she'd forgiven her mom for her past discrepancies and that Nancy should be a guest at her second wedding."
Jennifer cut her mother out of her life after Nancy released a tell-all book in 1999 From Mother and Daughter to Friends: A Memoir.
However, they have reconciled and Jennifer rushed to her mother's Los Angeles hospital bedside last year when she suffered a stroke.
