Kris Jenner is fearing the day when all her kids will be leaving home.

The self-proclaimed momager and "Keeping Up with the Kardaashians" reality star is mother to 35-year old Kourtney Kardashian, 34-year old Kim Kardashian-West, 30-year old Khloe Kardashian, and 27-year old Robert Kardashian. She also has two daughters by estranged husband Bruce Jenner, 19-year old Kendall and 17-year old Kylie.

Her youngest daughter Kylie is still living with her.

Attempting to swallow back tears, Jenner shared that time is just simply too fast, and that before she'll know it - everyone will have left home.

The 59-year-old momager shared, "[Kylie] keeps reminding me daily that she's 17 and there's only a few months left until she's 18. I ignore her because that's going to be weird and hard."

Her other daughters have also bought their own homes this past year, making her feel the emptiness even more.

In an interview with Oprah for the talk show host's "Where Are They Now" special, Jenner shared, "Khloé bought a house this year, and Kourtney bought a house this year, and Kendall bought a house this year, and Kim bought a new house this year. I do feel a little bit like it's an empty nest."

It certainly doesn't help either that Jenner has separated from her husband of more than 20 years, former Olympian Bruce Jenner, who is reportedly dating her former assistant and best friend.

But then again, Jenner doesn't seem to mind Bruce's love life anymore, as she is said to be in a relationship with 33-year old Corey Gamble. Gamble works for Justin Bieber's manager Scooter Braun's SB Projects.

Jenner recently celebrated her 59^th birthday with her new beau and witnesses said the two were very affectionate with each other.

The star even shared that she is extremely happy about her love life at the moment, saying, "Everything is wonderful."
