“Originally they wanted to fly everyone to Cabo San Lucas, Mexico, for a small barefoot-on-the-beach ceremony, but that plan was scrapped after details were leaked,” an insider tells OK!. And though Jen is annoyed that excited pals let her dream wedding plans slip out, the insider says that she and Justin have come up with an even better — and more private — idea: They want to elope and may just do it in upstate New York.

“Justin is all about New York. He moved there right after college and has never stopped loving it,” the insider explains. And now that he and Jen have decided to make it legal, the insider continues, “they are both incredibly excited; Jen can’t believe it’s actually happening. They’re writing their own vows, and she’s already rewritten hers countless times. Jen’s in such a super place at the moment. She’s on an all- time high.”

Eloping in upstate New York will make it convenient for Justin because, as the insider explains, “his friends and family are mostly on the East Coast, so they can have a party right after the wedding; he has a very big extended family. And Jen would want her dad and her mom there.” Jen’s then-estranged mother (who is recovering from a stroke) didn’t attend her daughter’s wedding to Brad Pitt, but, the insider says, “while she and Jen still have their issues, they’re getting on really well.”

Also on the party guest list: Jen and Justin’s mutual pals like Ben Stiller and his wife, Christine Taylor, as well as Robert Downey Jr. “And Jen wants to invite her close friends,” the insider reveals, “such as yoga guru Mandy Ingber, Andrea Bendewald and Chelsea Handler.”
