The pair started dating in January and have been inseparable ever since. Many have attributed Rob's recent confidence boost to his new romance. After years of staying out of the spotlight, the former reality star has returned to social media, posted pictures with his famous family, and has regularly been photographed out and about.

Naturally, the relationship hasn't been without its share of drama. Blac Chyna is the mother of Tyga's son, King Cairo, and the rapper is currently dating Rob's younger half-sister, Kylie Jenner.

Despite the early tension, sources say that the Kardashian-Jenner clan is pleased by their union.

"The family is really happy that they're together," a source previously told ET. "The changes Rob has made in his life are so good. They appreciate Chyna for that."

In a recent radio interview, momager Kris Jenner opened up about her son's girlfriend, saying, "I haven't really seen her that much and I don't know her as well as everyone else, but she seems like a really nice. I just haven't been around her too much. But, you know, he's been very, very happy lately and I think he's in a really good place. I don't know too much about their relationship."

Rob's sister, Khloe Kardashian, also put in her two cents on her talk show, Kocktails With Khloe, saying, "It sounds very dramatic, which it is, but I actually haven't seen Chyna for a few years. Her and I did not get into a fight. But I do love a good fight."
