Kylie Jenner Disses Blac Chyna, 'King Kylie' Instagram Name Change 'Steals' Baby Mama Love? Girlfriend 'Honors' Tyga's Son, Ready For Pregnancy?

Kylie Jenner just changed her official Instagram title to "King Kylie." Interesting - Tyga's adorable baby son is named King Cairo Stevenson. So, is the "Keeping Up With The Kardashians" younger trying to shade her boyfriend's bitter (ex) baby mama Blac Chyna (again)?

Apparently, 17-year-old Jenner's new "King" status has nothing to do with the former "Rack City" music video vixen. She just loves Trigga and little Cairo so much, she recently decided to honor them both on the popular social networking site!

"It's a tribute to Tyga's son, King. Kylie had a blast looking after him and chasing him around the basketball court at Tyga's game last weekend. She can't count the number of times she said 'King' at the game. 'Shoot the ball, King! You're so cute, King. You want to race me to half court, King.' She had the time of her life with him and thinks he's just as cute as a button," an alleged insider tells the infamous gossip webloid HollywoodLife.com. "So she decided to make that her name on Instagram for now. She's just showing the little guy some love."

But are things getting a bit too serious between the aspiring model and her 25-year-old rapper beau? Maybe Jenner's not trying to "shade" Chyna, but is she trying to replace the Instagram bombshell as a mother?

Hey - as long as King Cairo's content!

"Kylie's issues with Blac Chyna are between the two of them," the source continues. "That precious little boy has absolutely nothing to do with their issues. Kylie would never in a million years drag King into her issues with his mother. Kylie loves that little boy and thinks he's such an adorable young man."

Jenner heatedly denies that she's currently pregnant with the "Faded" emcee's second child. But can MstarsNews readers see the young Hollywood couple starting a family soon?
