Bachelorette sweeties Ashley Hebert, 28, and J.P. Rosenbaum, 35, are giddily gearing up for their walk down the aisle.

A source says Hebert not only scored star planner Mindy Weiss for the December 1 event in Pasadena, Calif. (airing on ABC December 16), she's gaga over her gown: "Ashley can't wait for people to see it!"

Invitees getting the first glimpse include show alums Emily Maynard, Trista and Ryan Sutter and (awkward alert!) ex-loves Ali Fedotowsky and Roberto Martinez.

Hebert and Rosenbaum have also both officially said their goodbyes to singledom: the bride and groom-to-be enjoyed respective bachelorette and bachelor bashes in Scottsdale, Ariz. the weekend of Nov. 17.

"Ashley and JP had their parties at the W, but they didn't celebrate together," a source tells Us Weekly. "The girls had quite the party! They had a stripper for Ashley and everyone got spa treatments."

Meanwhile, the source adds, "The guys hung out and went out for a steak dinner."

On Tuesday, Nov. 27, Ryan Seacrest joked on his radio show about receiving an invitation to the couple's wedding, which conflicts with the annual holiday concert Jingle Ball.

"I don't know them well. I got invited but…" he said. "That's an interesting scam isn't it? Invite people that you know or don't know so that they have to give you a gift."
