Happy Birthday Kylie Jenner! Now Face Blac Chyna’s Wrath! [PHOTOS]

Kylie Jenner is turning 18 on Monday, and when she becomes a legal adult, she's bound to do adult duties from now on. However, there could be someone blocking her way to the happiness she wants to share with boyfriend Tyga, and that someone is none other than Blac Chyna.

Ever since Kylie started going out with Tyga, Blac Chyna has been on the look out for advantageous moments wherein she could slam, challenge and beat Jenner on social media.

According to Starcasm, Blac Chyna is already preparing a slew of insults to throw at Kris Jenner's youngest daughter by the time she turns 18. In fact, the fuel between the two could have already gone to a whole new level when Chyna started posting revealing shots on Instagram to lure Tyga back to her and show Jenner that she'll never have what she physically has.

"It still irks Blac that Tyga's into little girls and gave up what he had with her for a teenager," a source told Starcasm. "But that's life. She just wants to know that even his little boo thang is turning 18, she'll never have a grown woman's body."

The source, who is apparently Chyna's close friend, went on to say, "Kylie will never have Blac's hips, chest, thighs or cakes. No matter how much money she spends trying to reconstruct her body, she'll never have what a sista is born with."

Additionally, Radar Online has learned that Chyna is also serious in trying to win the heart of her ex-lover Tyga back. One proof to this is her recent post on Instagram which features a snap of her clothed in a very sexy two-piece while basking under the sun. She captioned the snap "I know you miss me" to refer to her baby daddy.

Also, when Blac Chyna found out that Kylie and Tyga are going to celebrate the "KUWTK" star's birthday in Canada, she, too, booked a flight to Canada with the primary motive of throwing her own party there.

Chyna is also said to be very competitive when it comes to showing Kylie that she is better. On Tuesday, she shared a sexy snap of her body while drinking her detox drink. She captioned the photo, "Detox Tuesday I'm enjoying my @teamiblends tea cleanse, my favorite tea!"

She posted this just a day after Jenner shared the secret to losing and maintaining her weight. Kylie captioned the photo: "Ok soooo my birthday is in a few days and I'm getting back with my favorite Teatox Lyfe Tea."

Meanwhile, Hollywood Life has learned through sources that Kylie and Tyga's relationship is getting serious. Tyga is said to be pondering on asking Kylie Jenner to be the godparent of his son to Chyna, King Cairo. An insider even claimed that Tyga is very desperate to make Jenner part of his family such that he is willing to pay off Blac Chyna to allow this.

"Tyga already knows Blac is not going to go for this but he's willing to throw some coins at her to make her see this situation his way," a source said. "Tyga's in no way trying to replace Blac as being King's mother. He just wants Kylie in his boy's life and wants them to be connected."
