Khloe Kardashian is the ''medical advisor'' for her whole family.

The former 'Kocktails with Khloe' host was forced to make decisions about her estranged husband Lamar Odom's care when he suffered a near-fatal overdose last year, and her impressive calmness and strength in the tough time saw her loved ones change their wills as they felt confident she would be the right person to ensure their needs were met if they were incapable of making medical decisions themselves.

She said: ''This is kind of dark, but after that, my whole family changed all of their wills so that I would be their medical advisor.

''Because you don't know how someone reacts until you're put in that situation -- God forbid. No one should be put in those situations, but with that, I found strength from within.''

The 32-year-old star - who called off her divorce from the 37-year-old sportsman while continuing to care for him as he recovered from his overdose - admits it was a very tough time, but she somehow found the strength to remain calm.

She told Health magazine: ''I was super calm. And I was more like, 'It's greater than you,' and you just get strength.' ''

And Khloe believes her strength comes in part from her late father Robert Kardashian.

She said: ''I pray a lot. And I talk to my dad a lot.''

The 'Keeping Up With the Kardashians' star pressed ahead with her divorce earlier this year, and it is due to be finalised later this week.

And Khloe is happily in love with Cleveland Cavaliers player Tristan Thompson, who she has been dating since September.

She said: ''My boyfriend's a cutie. I'm 5'10'', and he's 6'9''.

''I love athletes. Someone who has the same interests as me, who likes to work out, like that's their hobby or their job, that's fine. Tristan is who I'm into. He's a little cutie.''
