Heidi Wants Lauren at the Wedding

In Monday night's episode of The Hills, Lauren told Heidi she thinks she's making a "really big" mistake marrying Spencer, when Heidi comes to invite her former best friend to the wedding.

Although we all know that Speidi already said their vows, the reality TV show is still leading us up to the big event.

The dress is picked out, the bridesmaids have been selected, Spencer and Heidi are getting therapy, and the groom claims to be the happiest he has ever been in his life, in Monday's episode.

Lauren, Stephanie, Audrina and Lo went out to lunch and discussed Speidi's wedding. "Maybe you'll send me BBMs L.C. said when all three girls said they would be attending the wedding.

Kelly Cutrone, owner of People's Revolution, got into an on screen fight with Stephanie at a Nylon party the gang attends. "Its Over," Cutrone said when Stephanie tried to defend her work on the job for Cutrone, from which she was fired a few episodes back.

Sunday will be the finale of The Hills and Lauren's last episode on the show. Previews for the episode reveal wedding bells and the return of Kristen Cavallari, who will be taking over for Lauren as the star of the show next season. MTV reports we will get a glimpse of what next season will look like on the season finale episode, but for the next few days it will be all speculation.
