Blac Chyna vs. Kylie Jenner Beef: Tyga & Ex-Stripper Back Together For Son's 'Family' Birthday, Teen Fling Ignores 'Cheating' Drama [Instagram PHOTOS]

Apparently, Blac Chyna's trying to get a rise out of 17-year-old "Keeping Up With The Kardashians" beauty, Kylie Jenner. But so far, such taunts have failed to upset the young reality starlet!

Rumors suggest that Chyna and rapper Tyga broke-up just a few months ago. Although several fans disapprove, the 24-year-old "Rack City" emcee then started romancing Jenner. The new Hollywood "couple" continues keeping their relationship on the down-low, but Tyga supposedly enjoys spoiling the brunette teen on weekly dates and private outtings.

But does Chyna want Tyga back, despite his overly flirtatious ways?

Chyna became the YMCMB superstar's "leading lady" back in October 2011. The two initially met at a The F.A.M.E. tour after-party with Chris Brown. They began dating shortly after, and eventually gave birth to baby son King Cairo Stevenson a year later (October 2012). They were engaged in December, but broke-up in August 2014.

That's when Tyga hooked-up with Jenner.

So if that's the case - what's up with these suggestive snapshots the former stripper recently shared on Instagram?

 Looks like the former couple's back together - cuddling and kissing!

The pics were quickly deleted, but Chyna later posted:

Rather cryptic, but still telling enough! Even if they're not exclusively dating again, the former lovers did celebrate baby King's 2nd birthday together. And "The Family" looks pretty happy about it:

Things appear rather intimate... is Jenner already out of the picture?

The "KUWTK" youngin' has yet to address anything on social media, which is probably for the best right now.
