The reality star filed for divorce after just 72 days of marriage last week and arrived back in the US on Friday, having cut short a promotional trip to Australia.
Kardashian headed up to Humphries' home town of Minneapolis early on Sunday, arriving at 6am. The couple spent the whole day together talking.
A source told TMZ that although the meeting was definitely not a reconciliation, Kardashian is 'conflicted' over the divorce.
“Kim has been saying even before she filed for divorce that she wasn't sure about ending the marriage,” the source said, while Humphries has previously declared he wants to make the marriage work.
'I'm committed to this marriage and everything this covenant represents,' the basketball star told Us Weekly last week. 'I love my wife and am devastated to learn she filed for divorce. I'm willing to do whatever it takes to make it work.'
