“Rob and Chyna,” the E! reality series starring Rob Kadashian and Blac Chyna, has premiered, and there are a few moments that deserve an “OMG” reaction. Here they are.

1. Rob and Chyna's first meeting

The two detailed how they first met and how Rob pursued Chyna. They said they were first introduced during Rob's half-sister Kendall Jenner's 16th birthday party. The two kept a friendly relationship at the time because Chyna was still dating Tyga, the father of her son King Cairo. Once the relationship with Tyga ended, though, Rob admitted that he immediately took the chance and let Chyna know that he would like to be more than just friends.

2. Their first big fight

The couple's first serious fight was so big, Chyna needed to ask Rob's mom, Kris Jenner, for help. The discord stemmed from Rob's insecurities. He went through Chyna's phone without her consent and asked why she changed the password if she had nothing to hide. Chyna was not happy about it, especially since she believes that there is no reason for Rob to get jealous over anyone. Chyna said she's busy running two businesses and raising his son, and she hardly leaves the house.

Things became uglier when Chyna found out that Rob was just projecting his thoughts. The Lashed entrepreneur learned that Rob was suspicious because he was texting other women and was curious to know if Chyna was also communicating with other guys. The two sorted things out, but not before Chyna asked Kris to talk to her son.

3. The baby's gender is revealed!

Rob and Chyna held off information about their unborn child, but the baby's gender was finally revealed during the show's premiere. The couple will have a girl! While Rob had expressed his desire to have a boy because he wants to have the same relationship he had with his father, Robert Kardashian Sr., with a son, he said he was happy that they are having a girl. He also said that he's sure he'll be just as close to her daughter.

“Rob and Chyna” airs Sundays, 9 p.m. on E!
