Happy couple: Fans hear the moment Kris proposes in the promo, but will have to wait to see the action

When Kim Kardashian headed to Bora Bora with her family and boyfriend Kris Humphries to film Keeping Up With the Kardashians, she had no idea she would be receiving a proposal.

And fans of the show are being teased with a tantalising audio clip of the 30-year-old responding in utter shock to the heartfelt offer in the new promotional clip for the series of Keeping Up With The Kardashians.

Kim can be heard gasping after Kris asks her to marry at him at the end of the video, though the moment itself is not shown.

It will be featured as part of the next season, however, which premieres June 12 at 10 p.m. (EST) on E!.

Tradition: Humphries asks Bruce Jenner for permission to ask Kim

And there are plenty of juicy trailers in the montage, including the moment when 26-year-old basketball pro asks Kim's step-dad, Bruce Jenner, for his permission for her hand in marriage.

'Really? You're getting that serious?' Jenner asks the 6ft9 NBA star, who bought a 20.5-carat Lorraine Schwartz sparkler to suggest he was deadly so.

Although Kim kept her engagement a big secret, the brunette, whose exes include Reggie Bush and Halle Berry's model ex, Gabriel Aubry, has enthused to Us Weekly about her future husband.

Anger: Kourtney defends her relationship with Disick to her mother

'He just has a really good heart," she said over Valentine's Day. 'There has to be trust and honesty and chemistry. If you don't have any of those, it's never going to work.'

Also in the clip, Kim's mother Kris Jenner is shown telling her daughter: 'This is no normal vacation. This is a huge test of your relationship.'

Tease: This is the footage shown when the proposal clip is played, but fans must wait to see the scene

The sixth season also sees the matriarch consider changing her name back to Kardashian, despite her union with Jenner, according to the trailer.

Meanwhile, she lambasts daughter Kourtney, 32 , for considering the thought of a second child with boyfriend Scott Disick, 28 , while they remain unmarried.

The pair already share adorable Mason, one, but club promoter Disick's drinking is a problem, another theme highlighted in this sneak preview.
