Kylie Jenner and Tyga may still be haunted by the rapper's previous relationship with Blac Chyna.

Radar Online reported that the 26-year-old rapper has once again communicating with his ex-girlfriend, with whom he has a son. "She and Tyga text and talk a lot - they're on much better terms than people think," an insider revealed.

Apparently, the 18-year-old "Keeping Up with Kardashians" star is not the only one who does not know about the constant communication between Tyga and Blac Chyna. Rob Kardashian, Chyna's current boyfriend, also is in the dark about their friendship.

"Blac's bragging to friends that Tyga's still in love with her and that the sight of her and Rob together is driving him crazy," the source added.

"It's true that Tyga hates Rob spending time with his kid [King Cairo] and he's always had a soft spot for Blac."

Earlier this month, Kylie Jenner took to Twitter with happy messages after Rob Kardashian and Blac Chyna's breakup was announced.

"Thanking God today for all my blessings. Life is so amazing," Jenner tweeted. "Put out good vibes and energy and you will receive!" the social media queen said in another tweet.

YHM previously reported that the social media queen was "livid" over Rob Kardashian and Blac Chyna's relationship. Apparently, the social media queen felt "super betrayed" when her half-brother started dating her boyfriend's ex-girlfriend.

Meanwhile, momager Kris Jenner is reportedly angry at Kylie Jenner's boyfriend, Tyga, for bringing guns near her daughter, according to IBT. In a report by TMZ, it was revealed that one of the rapper's friends carried a gun at a nightclub to protect Tyga.

"Kylie may think Tyga's bad boy image is cool but for Kris, she's not amused or impressed. Kris is furious that Tyga is riding with his security team and crew showcasing guns. It's not cool," a source said.

"Kris can't seem to figure him out. One day he's the sweetest kid ever. The next, he's doing stupid crap like this, making her worried about his relationship with Kylie."
