TYGA thinks Kylie Jenner is a "natural mother".
The 25-year-old rapper - who is dating the 17-year-old 'Keeping Up With The Kardashians' star - reportedly thinks his girlfriend has "mothering instincts" after seeing her interact with his two-year-old son, King Cairo.
A source shared: "She's got natural mother instincts for when she does have a baby.
"When King is around, Kylie lights up. She likes to hold him and she's read to him before at the house."
King Cairo - who the 'Rack City' hitmaker has with his ex-fiancé Blac Chyna - is believed to have built up an affinity with Kylie.
The source continued: "Kylie thinks King's the cutest little baby ever and she can't stop playing with his hair.
"Several weeks back she was over and she and Tyga were talking about some business but she was more interested in playing with King. She calls him 'King King' by the way and every time he sits on her lap she twists his hair."
Meanwhile, Kylie - who is rumoured to be pregnant with Tyga's baby - won't be getting the full seal of approval from two of her sisters if the rumours end up being true because of their individual struggles to get pregnant.
Another source told HollywoodLife.com: "If Kylie were pregnant, Kim and Khloe would be happy for her and absolutely sad at the same time.
"They're both having their own pregnancy problems, and for Kylie just to pop out a child that's totally unexpected and not planned would f**k up Khloe and Kim's psyche, especially Kim's."
