Hollywood super couple Brad Pitt and Angelina Jolie are planning a secret summer wedding — and the actress’ estranged father, actor Jon Voight, has been invited.

Shunning a star-studded affair, the notoriously private couple have instead opted for an intimate and non-religious ceremony at their retreat in Santa Barbara in early June, with only close family and friends present.

And Angelina — who has been estranged from her father since he accused her of having “mental problems” following her split from Billy Bob Thornton in 2002 — has reportedly asked him to walk her down the aisle.

A source said: “Since they started talking by phone in January, Angie has thought about asking Jon to give her away.

“When Angie and Brad started seriously discussing a wedding, the issue of Angie reconciling with her dad came up again and again.

“Angie came around after her brother intervened and strongly urged her to bury the hatchet.”

Although a quiet wedding is planned, there will be a small selection of celebrity guests.

“George Clooney and Matt Damon will be going, but other than a few film executive friends, it will be a Hollywood-free zone,” the source tells one British newspaper.

“Angelina and Brad want a low-key ceremony. No one will know it’s a wedding until they arrive.

“Instead, they are billing it as a summer barbecue and joint birthday party for Angie and daughter Shiloh.

“Brad is picking out cases of his favorite wine from nearby Santa Maria and Paso Robles and Angelina is busy organizing the cake.”

Voight, 69, recently said of his daughter’s (unconfirmed) pregnancy, “I’m very excited, and I’m sending my love to the family.

“They’re getting to be a bigger family — it’s great!

“It’s nice to see people embracing family and loving that whole process.”
