Heidi Montag and Spencer Pratt Is that the sound of wedding bells we hear reverberating through The Hills?

It might be, if Heidi Montag and Spencer Pratt really do tie the knot this time around.

But guess who's going to be a no-show at the reported nuptuals?

Frenemy, Lauren Conrad.

Yep, The Hills hottie has said thanks, but no thanks to Speidi's wedding invite.

"I'm not planning on going," she told People mag.

"It was very nice of her to invite me, but I think she didn't really expect me to come," she continued.

The couple are reportedly getting hitched at a sunset ceremony at the Westminster Presbyterian Church in Pasadena, California, this Lauren ConradSaturday.

It's been a long time coming for the lovebirds, and it seems Audrina Patridge is happy to be one of the wedding guests.

"They're two peas in a pod... I can't see either of them with anyone else," Audrina Patridge told the mag.

"They just work together. They seem to click and that's all that matters," added Brody Jenner.

So what can we expect this time around?

According to Spencer's younger sis, Stephanie, they're actually keeping it old-school and very tame: "It's very traditional, and they want to keep everything white - Heidi's dress is white.

"I hope no one objects."
