Kim's wedding dress

They are the most photographed family in the world but somehow they have managed to keep a few things private, well, until their show this Sunday at least.
Keeping Up With The Kardshians is back and a new trailer is revealing there was a lot more going on behind the scenes than fans know.
From Kim's first wedding dress fitting to Khloe coming to grips with her new post-marriage life, there are plenty of tears, cheers and a lot of yelling along the way.
Behind the scenes: Keeping Up With The Kardshians is back on Sunday and a new promotional clip showing fans there is more going on with the famous family than they thought
E! posted the two minute trailer on online on Friday and it was immediately clear this has been a big year for the reality clan.
In the sneak peek, preparing for Kim's wedding is a main feature including the very first time the star puts on her gown.
Caught on film, the 33-year-old is surrounded by the female members of her family who all gasp as she steps out of the change room in her dress and her cathedral length gown.
But while Kim's marriage begins, Season 9 also follows the fallout from the end of Khloe's - and it is far from smooth sailing.
Struggling to overcome her split with Lamar Odom, an emotional Khloe vows to solider on, but as the clip shows, is dealt another harsh blow when her Encino house is robbed and questions arise who would have done it.
Sitting on the floor looking defeated Khloe says: 'I want to know who is taking advantage of already such a [bleep] situation in my life.'
Feeling her daughter's pain Kris Jenner breaks down in tears in the sneak peek saying: 'I just don't know how one person deals with everything she is dealing with.'
However, one way Khloe finds to deal is trying to fire Kris as her manager in a dramatic scene.
The 29-year-old screams: 'I'm going to get someone new to run my s** cos you're not on it.'
Clearly this season is a tough one for Khloe and big sister Kim also expresses her concern.
Kim tells her sister: 'I'm afraid for you cos you live a double life.'
But the 29-year-old says she is moving past her relationship with Lamar, who reportedly struggled with substance abuse issues: 'A double life is what I did, constantly hiding.'
But with the bad comes the good, and as her almost brother-in-law Scott Disick points out Khloe is a 'hot item in the rap community'.
And she does not stay single for long, with the trailer confirming Khloe has in fact found love again with rapper French Montana.
Khloe is not the only one who is going through change, with the sneak peek revealing Kendall Jenner is branching out too.
This season the 18-year-old will take herself off on a solo trip to London and purchases her own home in the Hollywood Hills.
And it is not just the ladies of the family that will have their trials and tribulations.
The promo also reveals that despite Kris and Bruce Jenner saying their split was amicable, there have been heightened tensions between the pair.
And they are not the only ones with friction, as in one scene Kim uses a rare expletive when talking about her step brother Bordy.
Demanding Bruce intervene, she says: 'Will you talk to Brody because I'm to the point where I will go the f*** off on him.'
Not that Brody has time to care, he is too busy getting involved in bar fights to protect his sisters' in Thailand.

Keeping Up With the Kardashians, premieres this Sunday on E!.
