The couple, who are expected to tie the knot later this month, asked guests who will be invited to the intimate ceremony to make charity donations in lieu of buying them presents, reported Contactmusic.
"Jen and Justin's wedding will be an intimate affair with close friends and family, and Jennifer's ex-husband Brad Pitt is definitely not on the guest list.
"They have also requested that instead of gifts, guests donate money to a children's hospice," a source said.
The pair are heavily involved in their wedding planning and are even writing their own vows.
