Tyga & Blac Chyna Cheating Scandal? Rapper 'Creeping' On Young Kylie Jenner With Ex Baby Mama, Back Together After 'Kissing' Instagram PHOTOS

Did negative backlash surrounding Tyga's blossoming relationship with "Keeping Up With The Kardashians" teen Kylie Jenner finally hit a breaking point?

UPDATE: Blac Chyna Baby Daddy Relationship? 'You Guessing & You Right!'

The infamous gossip webloid MediaTakeOut.com just reported that the Hotel California rapper may already be cheating on his new 17-year-old girlfriend... with ex-lover, Blac Chyna!

Tyga already has a child with the former stripper. Another weird coincidence - Chyna's good friends with Jenner's older sister, Kim Kardashian.

So, why does MTO believe the YMCMB superstar's creeping around behind the young beauty's back?

Because the "Rack City" video vixen recently posted some rather eyebrow-raising snapshots on Instagram... before quickly deleting them, of course:

Interesting... definitely looks like Chyna is cuddling-up and kissing her ex-beau in these lovey-dovey pics! Not sure how old the images might be, though.

Still, why would the aspiring model instigate drama if the relationship's done for good? Several fans are wondering the same question...

Funny - just a few days ago, Tyga also left a "smiley face" on this post:

 I want you, to turn up on me Every night when I see you.....

So who knows what's really going on. Perhaps Tyga's relationship with Jenner is fake - something to merely kick-off her own music career.

Rumors initally suggested that Chyna was "jealous" of the much-younger Jenner... perhaps this is the ultimate form of revenge?

Tyga remains mum on Twitter about the whole thing (but not when it comes to his potential beef with YMCMB and Lil Wayne...).

Stay tuned!
