It took the 30-year-old rap star two years and $2 million to finalise his divorce with ex-wife Nadeen Kharpouch - whom he married in 2007 - and he's insistent that he won't sign a prenup in the event he marries his on-off girlfriend.
He said: ''I just settled a divorce and gave somebody money.''
And then, speaking to gossip website TMZ, he said there would be ''no prenups'' were he and Khloe, 30, to tie the knot.
This comes shortly after it was reported Kris Jenner wants Kourtney and Khloé Kardashian to have a double wedding.
The 59-year-old manager is said to think Kourtney should marry Scott Disick and Khloé should marry French during the same ceremony for an E! reality special.
A source said: ''Kris pitched the idea to Ryan Seacrest [who produces 'Keeping Up with the Kardashians'] and E! - of course they were over the moon with the idea.''
According to the report, Kris thinks the footage will be a big hit with fans of their reality TV series and bring in even more money than her other daughter Kim Kardashian West's nuptials to Kanye West, which were only partially televised.
The insider explained to Life & Style magazine: ''Kris has guaranteed everyone a big payout. She had everything planned before her daughters even agreed to it.
''This will be bigger than Kim and Kanye's wedding - and the ratings will be record-breaking.''
