The 'Keeping Up With the Kardashians' star has penned a tribute to her mom - who is dating Corey Gamble - on her 60th birthday, and explained the ways the showbiz matriarch is a typical Scorpio, including her sexual prowess.

Noting Scorpios are the "most sexual sign", she wrote: "She's good in bed!!! ... Unfortunately, Kim [Kardashian West] heard my mom & Corey going at it, and I can confirm that this is the truth. Haha! (sic)"

Khloe also praised her manager's "manipulative" streak and said she gets her own controlling ways from her mother.

She said: "Scorpios are all about control. Have you met Kris Jenner? That is her to a T. She is in control of everything, at all times. I definitely take after her in that respect. Thank you, mama...

"One major thing about Scorpios is that they tend to be pretty manipulative - and damn, does Kris know how to get what she wants, LOL!!! She can sell ice to an Eskimo."

The 31-year-old star concluded the post by praising Kris for being the "sweetest, loving, most forgiving" person.

And she wasn't the only member of the family to pay tribute to the matriarch.

Her sister Kourtney Kardashian shared a family selfie and thanked her mother for the thinks she has taught her.

She wrote on Instagram: "Happy 60th Birthday to the bo$$iest baddest momager alive! You have taught me how to celebrate life, make memories and live in the moment and I cherish everything I learn from you every day.(sic)"

And Kim Kardashian West - who is pregnant with her and husband Kanye West's second child, a brother for two-year-old North - praised her "best friend".

She posted: "Happy 60th Birthday to my best friend & mom @krisjenner.

"Now that I'm a mom I have realized how hard your job is & no one does it better than you! I love you so much!(sic)"
