Kris Jenner insists Khloé Kardashian is staying ''strong'' after she filed for divorce from Lamar Odom last week.

The 'Keeping Up With the Kardashians' star is adamant her daughter is doing fine after terminating her four-year marriage with the basketball hunk, citing ''irreconcilable differences''.

She said: ''Khloé really is so great. She's strong and ... the good news is that she's busy and you know, keeps her real busy. But she's good.

''She's got such a big heart but she also is very sensitive. She's got that tougher exterior and sensitive inside, but she's good. She's got all of us all around her and I'll see her later, and yeah, she's good. I was with her yesterday and she's a gift. She's one of my biggest blessings.''

The 29-year-old star has been spotted without her wedding ring on for three weeks following allegations earlier this year that Lamar, 34, cheated on her with multiple other women and has also battled a cocaine addiction.

Speaking to E! News, Kris added: ''I think that when you have a tough decision to make and you finally make it, it's always a relief to come through that process, but it is a process. So we'll see.''

Khloé has also reportedly asked for her surname to be changed from Kardashian-Odom back to Kardashian.

The couple have no children together and have reportedly signed an ''ironclad'' prenuptial agreement, which will help to divide all their significant assets.
