Well, E! certainly has changed its promo plan!

A new trailer for the upcoming season of Kourtney & Kim Take New York premiered Tuesday, and its focus is on the "unraveling" of Kim Kardashian and Kris Humphries relationship.

Kim filed for divorce from her husband of 72 days on Oct. 31. The couple moved to NYC (and moved in with Kourtney and boyfriend Scott Disick) directly after their August wedding.

Kourtney Kardashian is shown in the preview telling Kim "If it's not meant to be it's not meant to be," as the booming voice of a narrator preaches that Kim and Kris will see their future "unravel, because not every fairytale has a happy ending."

If you recall, Kim and Kris' wedding special was called A Fairytale Event.

The preview shows Kim getting upset with Kris for partying too much. Rumors spread that this was a problem for Kim over the last few months.

We already got a peek at her ridiculously taut tummy, and now Mariah Carey is spilling the beans on how she lost a whopping 70 pounds just 6 months after giving birth to twins Moroccan and Monroe Cannon.

Mariah appeared on Tuesday's episode of The Rosie Show on OWN, and the 42-year-old singer revealed that her new physique is the result of a strict diet and exercise routine.

"In the beginning, when I first had the babies, I had so much edema … water and swelling. Most pregnant woman have that just in their feet," Mariah told Rosie. "I didn't think I would ever be the same person." After the twins were born, Mariah went on the Jenny diet plan (formerly Jenny Craig), and she is thrilled with the results. "The first week, I lost 40 lbs. of just water," she said. "It was just water, initially. When I started with the program, I lost at least 30 lbs. of weight that needed to be lost."

"I never weighed myself," she explains. "People will think I'm a liar but it's true. This is another cliché phrase, I'm a big boned girl … I'm tall and so I always weigh more. I would tend to go, 'Does this size dress fit me that I wore three years ago? I'm good, let's go.' I would go by what it looked like, how I felt."

Rachel Zoe and husband Rodger Berman were snapped going for a stroll on Robertson Blvd with their 7-month-old son Skyler, and the happy family appeared to be enjoying the brisk fall weather.

It's no secret that Rachel rocked sky high pumps right up until her due date, and it sounds like she expects the same of her celebrity clients! Jennifer Garner, who has been styled by Zoe for years, recently spoke to InStyle and revealed that Zoe is against her wearing maternity dresses, despite the fact that she's sporting a serious baby bump. "Rachel Zoe is so determined to not put me in maternity clothes," she joked at AFI Festival's Butter screening last weekend.

She may be tough, but she does have one of the best dressed celebritots out there, right?

Amber Rose is clearing the air about the months following her break-up with Kanye West.

The two dated for two years, and Rose, 29 hints that after their break-up, she and West, 34, swapped exes with Kim Kardashian and Reggie Bush.

Kardashian, 31, and Bush, 26, split in 2010 after years of dating as well. Rose says that she and Bush were each other's rebounds:

"I had broken up with Kanye, and he had broken up with Kim and we met right after. We were both going through a hard time, and we were each other's rebounds, basically. It was brief. It was nice. He's a great guy."

AND, Rose implies that West and Kardashian hooked up, too. In summer 2010, West filmed a cameo on Kardashian's reality show, Kourtney & Kim Take New York.

When asked by Williams if the two spent some (ahem) quality time together, Rose shrugs, smiles and says, "I mean, come on. We'll keep it cute. ... We'll keep it cute."
