Blac Chyna, Tyga Break-Up [UPDATE]: Kylie Jenner’s Boyfriend Celebrates New Year With Reality Star In Las Vegas; Kim Kardashian's BFF Also In Town With Amber Rose

Following the much talked-about Blac Chyna and Tyga break-up, the rapper opted to welcome the New Year with his rumored girlfriend Kylie Jenner in Las Vegas. His baby mama was also in town with best pal Amber Rose for a club appearance.

The 25-year-old rapper was spotted with 17-year-old "Keeping Up With The Kardashians" star Kylie Jenner at a mall food court in Las Vegas. Meanwhile, Tyga's ex-fiance Blac Chyna was also said to be in town for an appearance at Ace of Diamonds with Wiz Khalifa's ex Amber Rose.

To celebrate the New Year, Kim Kardashian's BFF Blac Chyna reportedly treated her followers with an Instagram photo showing off her cleavage in black and white filter. She captioned the photo: "Happy New Years @kinggoldchains!"

The handle @kinggoldchains is Tyga's official Instagram account.

In a report from TheyBF.com, it was speculated that Blac Chyna was trolling her ex as she just wants to "get nasty" with his underage rumored girlfriend Kylie Jenner.

But Blac Chyna later deleted the post.

It can be recalled that Blac Chyna, Tyga's break-up has allegedly resulted to the supposed plan of the rapper to file for full custody of their son, King Cairo, after he accused Kim Kardashian's BFF of constant partying and clubbing, a TMZ report said.

Kylie Jenner's boyfriend reportedly said that his ex-fiance has been leaving their son to his nannies while she's out with her friends.

Tyga allegedly got even more furious when an Instagram video circulated showing Blac Chyna and Amber Rose twerking in a club with their son's godfather Chris Brown.

Soon after Blac Chyna, Tyga's break-up, the rapper was reported to be dating "Keeping Up With The Kardashians" star Kylie Jenner. But rumors claimed that the family of the reality tv star disapproves of their relationship.
