Hollywood Exclusive by Marilyn Beck & Stacy Jenel Smith

"The Hills" star Lauren Conrad, who's had an infamous ongoing feud with former friend Heidi Montag and her now-husband Spencer Pratt, was pictured in Us Weekly attending their wedding, but … Spencer's sister, Stephanie, tells us there's still no reconciliation.

"At the beginning of this season, I was trying to take Heidi places with us, and it took a toll on my friendship with Lauren. She was like, 'Stephanie, I don't want to be friends with her.' I think it's all over, though. I think they just know they can't be friends," says Pratt, who also stars on the MTV reality show, which is heading toward its May 31 finale.

At least some good came out of the wedding. Stephanie, who caught the wrath of Spencer for being friends with Lauren, tells us their sibling relationship has definitely improved. "Last season was awful for me. I was crying all the time because Spencer was being mean to me and Heidi wasn't talking to me, because she always does what Spencer does. But Spencer's been super nice to me ever since he's gotten married. I think now that they're very secure in their relationship, they've both been really happy and nice to everyone."

For now, the cast is regrouping since Lauren announced she would not be returning to the show. "She has a boyfriend, she has a great life, and she wants to keep it private. It was a little shocking she decided to leave, but she's been on TV for six years. I think it's definitely going to change the show a lot. She was kind of like our voice of reason. I feel like it's going to be really chaotic now," claims Pratt, who can next be seen hosting the MTV Movie Awards pre-show along with Lo Bosworth. The Awards show is set for May 31.

"We'll be doing live hits. I really want to meet the cast of 'Twilight.' I'm a big fan of the books. It was a good escape when things were going bad on the show."

FAMILY AFFAIR: With Shaun Cassidy writing and producing the upcoming ABC Family Channel show "Ruby and the Rockits" — starring David and Patrick Cassidy as former teen idols and Alexa Vega as David's daughter — can Cassidy matriarch Shirley Jones be far behind? "The plan is to write Shirley in as Grandma," according to Jones' husband Marty Ingels.

He tells us that the July 21-debuting show is well stocked with Cassidy family members behind the scenes as well as in front of the cameras. There's Shaun, of course. "He has one project after another," Marty says. "Walt Disney's old office is his office … All of Shirley's children are successful.

"Ryan is doing the sets. Shaun's daughter Caitlin is doing the makeup. Don't talk to me, I'm invisible," he adds. "How can you not write in the old Jewish guy in the other room? They don't like me."

Long-standing family friction aside, Marty says the half-hour show is "hysterical. David Cassidy is back with his hair thinning. Patrick has a used car agency."

Meanwhile, Shirley is looking forward to a string of concert dates with Florence Henderson. Yes, "The Partridge Family" and "The Brady Bunch" mothers onstage together for the first time. "At first, Shirley wasn't terribly excited, but it's interesting, the two of them together, buddies singing and taking shots at each other. These kind of theme concerts are doing very well. They open in November in Indianapolis."

SEIZING THE DAYS: "Southland" actor Kevin Alejandro is certainly making the most of his hiatus from the NBC cop drama. After wrapping production on the show, "My wife and I went to Hawaii for 7, 8 days," he says. Then he left for Atlanta, where he's been shooting a guest star part on Lifetime's forthcoming "Drop Dead Diva." And once he's done with that, "on the 28th, we're going to Costa Rica for 10 days, surfing with friends." He'll also be working out and pampering himself. "I want to be in the best shape I can be before starting shooting again. This is my break, and it's time to do it," he says. "Southland" goes back before the cameras in mid-July.

HAIR TODAY: Casting forces have been interviewing hairstylists to fill the post of assistant to a celebrity hairstylist on a forthcoming reality competition/elimination show. They want someone over-the-top who can add color to the proceedings, and we don't mean the kind from a bottle. "Think Tim Gunn to Heidi Klum," say casting notices.
