After a week of silence, Kylie Jenner and Blac Chyna resumed their feud on social media as it has been reported that the two are fighting over Tyga. The rapper is Blac Chyna's ex and the father of her son King Cairo, while Jenner is rumored to be dating Tyga.

Early in the weekend, Chyna posted a picture of her son on Instagram and captioned the picture, "Mine."

Not long after, Jenner posted a picture of Tyga posing with Justin Bieber. She captioned the shot, "Da boys."

Meanwhile, Tyga did not acknowledge the mother of his child at all. Instead, the rapper chose to post a picture of him with his mother and captioned it, "Happy mother's day to my twin!"

Jenner's feud with Chyna appears to be getting bigger as several family members are now getting involved. Tyga's grandmother, Kim Nguyen, recently spoke to the Daily Mail and said that she approves of Jenner.

"We all love Kylie and think she is so much better for Tyga than Blac," said Nguyen of the 17-year old reality star. "Yes, she is King's mom, but Blac just wasn't a very nice person and Kylie comes from a much better family."

"She is such a sweet, lovely girl and seems to adore Tyga. So we didn't mind him splitting up from Blac. It was a relief for us all," she adds.

Now, Chyna's mom Tokyo Toni is firing back at Nguyen's comments, as Mirror.co reports that Toni took to Instagram and wrote, in a now deleted post, "They are talking Kylie comes from a better family…how? Her parents are divorced, her dad wants to be a woman…she's 17 and has already had lip injections."

Before she removed her post, Tyga reportedly left a comment and warned her to "stay off social media."

"All these stories are fake and you should know that…I've yet so say anything disrespectful about your daughter or u. And I don't plan on it," he wrote.

Referring to his son, he is said to have added, "King is the bigger picture. Please keep the peace for his sake."

Chyna later tweeted, "Tyga Do as you say…and don't address family issues over social media."
