Hebert is currently engaged to JP Rosenbaum, whom she met on The Bachelorette last year.
The couple are rumoured to be planning a fall wedding and Hebert has now admitted that she wants Spivey - whom she met on Brad Womack's second season of The Bachelor - to be a part of it.
"She's like my best friend," she told Wetpaint. "She'll be there."
Rosenbaum added: "There will definitely be a lot of invites. Wedding party? We haven't really thought about it yet. Probably, just Ashley."
Hebert and Rosenbaum recently revealed that they are excited about having children together.
