LOS ANGELES, Calif. -- "The Hills" are alive with the sound of wedding bells... again!

The third time will hopefully be the charm for Spencer and Heidi of the MTV reality show "The Hills." Access Hollywood caught up with the cast of the show at their PaleyFest09 panel Tuesday night where they dished the dirt on who was invited... and who wasn't.

Among the invitees was Spencer's long-time friend and short-lived enemy, Brody Jenner .

"Yes. I will be going [to Spencer and Heidi's wedding]," Brody told Access.

"I'm not gonna be a groomsman, I don't think that would be the best idea. I was thinking about being in the wedding but I decided no, I'll just attend."

As for throwing Spencer a bachelor party, Brody didn't think one was in the works.

"No, what I heard through the grapevine... is that Heidi wasn't gonna let him, or something. I wanted to go to it, I thought it'd be a fun time... but it may not happen. But you never know, you never know what to expect."

Spencer's sister, Stephanie, will be attending the wedding, although she wasn't convinced that the couple would make it down the aisle.

"I don't know if it's this weekend. I hope it happens but they keep changing their minds and I can't keep up," Stephanie explains. "There's a possibility that Heidi's going marry, like, Brad Pitt ! It's just too confusing with them."

If the wedding does take place this weekend, Stephanie will be a bridesmaid.

"We did have our bridesmaid talk. I get to be a bridesmaid and I think Holly's the other bridesmaid."

Heidi's biggest frenemy, Lauren Conrad , also got an invitation, but wasn't planning on attending.

"I'm not going [to the wedding], no," Lauren told Access at Us Weekly's "Hot Hollywood" party on Wednesday night.

Another surprising wedding guest is Lauren's roommate, Lo Bosworth.

"Yes, I am [going to the wedding]. I will be sitting, watching," Lo dishes. However, Lo hasn't quite decided on the perfect gift.

"I still have a few more days. I haven't quite figured out what would be appropriate for them."

Also attending is Heidi's on-again, off-again friend, Audrina.

"I'm attending," Audrina tells Access. "Good for them, they're finally really getting married."

So, who from "The Hills" was snubbed from Heidi and Spencer's guest list?

"You know, I just heard it was this weekend so [I'm] obviously not [attending]," Whitney Port says with a laugh. "We see each other once in a while, but I'm not super close with them, but I wish them all the best."
