Insta-feud! Kylie Jenner and Blac Chyna Exchange Jabs Over Mother's Day Weekend -- Read Tyga's Reaction

Kylie Jenner's feud with Blac Chyna​ knows no holidays! The Keeping Up with the Kardashians star kept the shade throwing going on Mother's Day when she posted a photo that seemed like a subliminal jab​ at her man Tyga's ex and baby mama.

Early in the weekend, Chyna posted a picture of her adorable son, King Cairo, fathered by Tyga. She captioned the sweet pic "Mine."

Not long after, Jenner posted a pic of her own, which showed King Cairo's daddy -- and her current boyfriend -- posing with Justin Bieber. Jenner chose to caption the picture "Da boys."

Tyga, meanwhile, did not acknowledge the mother of his child at all over Instagram, instead posting a picture of him with his own mother -- just the latest proof that it's always shady in Southern California!
