Wetpaint Entertainment exclusively revealed that Tamra Barney and fiance Eddie Judge’s joint bachelor-bachelorette party was going down recently in Las Vegas. Now, we can also report that not every one of Tamra’s Real Housewives of OC co-stars were in attendance…because not all of them were invited!

Despite Tamra reconciling with her former nemesis, Gretchen Rossi, Gretchen’s presence was not requested. “She wasn’t invited,” a source confirms to Wetpaint. As Gretchen herself tweeted, “Guess I didn’t make the cut.” Tamra swears there is no issue currently between her and Gretchen, but the two haven't apparently reconciled enough to party together quite yet. 

Also not invited (to no one’s surprise): Tamra’s current nemesis Alexis Bellino and newcomer Lydia McLaughlin.

In the house, however, are Tamra’s cast mate and good pal Heather Dubrow and Heather’s husband, Terry. “Both of them are there,” says the source. “Tamra and Eddie have a great time with them.” You can obviously tell if you check out the photos from the event!

And what about Vicki Gunvalson? Although she and Tamra used to be BFF’s, they’ve been feuding lately over Vicki’s boyfriend, Brooks Ayers, and a soured business partnership.

“Vicki was invited, but she was unable to come,” the source explains. “She was definitely invited, though.”

As for the hijinks currently ensuing at the Sin City bash? We’ll just have to watch what happens. We hear that Bravo is in town filming the whole thing!
