Blac Chyna and Rob Kardashian have had some serious blowout fights since getting together more than a year ago. They have broken up, made up, split up, shacked up, and everything in between before Chyna got pregnant, during her pregnancy, and even after she gave birth to their daughter, Dream. Now, new reports suggest that another split is inevitable -- and this time, it might be for good.

Photos of Blac Chyna with a 'mystery' man surface

Although things seemed to be going well for the reality stars, several reports surfaced over the weekend, all suggesting that Chyna was spotted with another guy on Super Bowl Sunday.

Sources claim that Chyna was all over some dude and that she talked about her relationship with Rob, mentioning that the two were talking but that they weren't living together.

Strangely enough, these reports come just one week after rob and chyna celebrated their one year anniversary. Rob posted a sweet message to his lady love on Instagram just days before she was allegedly seen canoodling with some other guy.

The Kardashian sisters reportedly hire a private investigator

Several reports indicate that Kim, Khloe, and Kourtney Kardashian decided to help their brother out by hiring a PI to check up on Blac Chyna. Although Rob's sisters have grown to love and accept Chyna, sources have said that the girls are willing to do whatever it takes for Rob to find out what's really going on when he is not around.

Whether or not these rumors are true, there is no denying that Rob and Chyna's relationship has been tough from the jump. While the two might love each other very much, they seem to have a really hard time communicating, and they both seem to have pretty nasty tempers. Fans hope that the two can work things out, especially for the sake of their baby girl, but no one will be surprised if the two break things off once more.

Will Rob Kardashian delete his social media posts again?

One sure-fire sign of a Rob and Chyna split is social media. Nine times out of ten, Kardashian will delete every single post and photo about Chyna when the two are having issues. If any of the aforementioned rumors are true and Chyna has been cheating on Rob, expect the deleting to begin at any moment.
