Guests already at the chateau include Brad’s mom Jane and dad Bill — and top jeweler Robert Procop, who made Angelina’s engagement ring.
The bash is said to be for Jane and Bill’s 50th wedding anniversary — but locals think otherwise and claim there is a “real buzz” there.
A source said: “Brad flew in to oversee preparations but they’re all here now. They say it’s for Jane and Bill, but some think this could be it. Even Angelina’s private jeweler is here.”
