Pregnant Kylie Jenner An 'Emotional Wreck': 'She Feels So Alone!'

The stress created from a top-secret pregnancy is starting to take its toll on 20-year-old expectant mother Kylie Jenner!

“Honestly, Kylie is just an emotional wreck right now,” a source close to Jenner told RadarOnline.com exclusively. “She does not know what to do or who to trust, and she is just so vulnerable right now."

The makeup mogul's youth and inexperience in the face of an enormous change may be to blame for the breakdown, the insider said: "Her age is really starting to show."

According to the source, Kylie – who is several months pregnant with 27-year-old boyfriend Travis Scott’s baby – is "scared."

"She does not know how to be an adult, let alone be a mother," the source explained. "She’s feeling so alone!”

While Kylie has been attempting to lean on her momager, Kris Jenner, 62, has been too busy to give her needy daughter all the attention she craves, the insider claimed.

“Kylie is trying to rely on Kris, but Kris has made it clear she simply does not have the time to deal with it."

As RadarOnline.com previously reported, Kris was planning a big pregnancy reveal and spinoff show for her daughter. But Kylie has been growing impatient of staying low-key after years of shining in the spotlight.

“Kylie is just tired of being in hiding. She hates the fact that she has to keep it a big secret for Kris,” the source added. “It’s created a lot of tension between the two of them and there was already a lot of tension to begin with.”
