Watch: E! Unveils Trailer For New Reality Show "Rob & Chyna"

For those among us who are dying to know just what caused the "big fight" that recently played out on social media between Rob & Blac Chyna, you just may get some insight...

In this exclusive first look at E!'s upcoming six-episode docu-series Rob & Chyna, the engaged couple and parents to-be get in a blowout fight as their prepare for the birth of their baby.

"I fell in love with you because I know how good you are and how loyal you are," Rob tells Chyna in the video.

Cut to Chyna screaming at Rob over the phone, "Are you still texting bitches, yes or no?" before she slams the door on him. Yikes!

In addition to their tiff, which caused some breakup rumors a few weeks ago, we see the lovebirds laughing, loving and sharing lots of sweet PDA. Rob even kisses Chyna's bare baby bump as she asks him, "Are you ready to be a daddy?"

The clip ends with the tagline, "They're cute, they're complicated and they're about to become family." (E! News)

The whole thing, though a major mix of publicity & made for tv drama, looks kind of interesting and definitely looks like a show to watch!
