That sound you hear is Kris Jenner and all the dollar signs rolling in front of her eyes.

Kourtney Kardashian and Scott Disick are reportedly finally planning to marry, with the 'Keeping Up with the Kardashians' most noted cynic said to have accepted a proposal from her long-term partner with who she has children Mason and Penelope. And  of course we're already hearing rumours about where the pair are planning to tie the knot and when. So far the answer to when is 'very soon', i.e. once cameras are back to start filming, and the where is apparently at close friend Joe Francis' luxury five-star Casa Aramara property in Punta Mita, Mexico (or so says Joe Francis because he wants some publicity).

'Insiders', ever the source of truth and intellect, say Kourtney 'finally agreed' to tie the knot with Scott because things between them are 'going really well' and she also 'wants to offer commitment to her partner following the tragic deaths of his mother Bonnie in October and father Jeffrey' less than three months apart in early January.

According to Life&Style magazine: 'Kourtney realised that she's all he has. It's made her see things differently. This is the perfect time for Scott and Kourtney to get married.'

Though the couple are planning an intimate wedding, they of course won't spare any expense and will splash out $100,000 on round trip private jet flights for their loved ones, as well as $30,000 a night on accommodation. Though it is unknown when exactly the two will marry, the magazine reports they already celebrated their bachelor and bachelorette parties last month.

Kourtney and Scott are said to have hired wedding planner Sharon Sacks - who oversaw the nuptials between Khloe Kardashian and her now-estranged husband Lamar Odom - with family friends Lorraine Schwartz and Vera Wang set to design their wedding rings and her dress respectively.
