Relationship issues, growing up and car woes greet the gang of "Rich Kids of Beverly Hills" after their adventure-filled trip to China.

On Sunday, the "Rich Kids" crew is back in their home front Los Angeles, where they immediately start off with the drama. First, Dorothy Wang filled in EJ Johnson with the group's shenanigans in the Asian country. Wang candidly admitted to Johnson, who wasn't able to join the trip, that traveling with many people is an argument-laden catastrophe waiting to happen.

"Like in L.A., what do we have to fight about? Like who gets their La Scala chopped salad first?" Wang said.

Dorothy's boyfriend, Cooper, was also unable to join the trip, but she said they are still on good terms. Then, the two friends busted out their dance moves, and Dorothy said she loves dancing because she can "believe I'm Beyonce" even for just 15 seconds.

After her dance-off with Johnson, Dorothy next visited BFF Morgan Stewart in her newly decorated home. Morgan, however, wanted the latest news on Dorothy and Cooper, saying that she and the rest of the gang "want to make sure that Cooper is great to you."

Morgan, in her trademark feisty way, told Dorothy that she thinks Cooper doesn't treat her well, saying that any one "needs to be cared for the same amount that you care about that person."

Then, Morgan is off to a day at the nail salon with her mother, Susan. But their bonding time soon turned sour after Susan brought up the fact that Morgan is turning a year older. Morgan, on the other hand, bristled at the thought that her mother has been checking her blog every day.

Dorothy and EJ met up again, but this time to shop for EJ's new car. EJ has been sharing his mother's car ever since he returned to L.A. and he's dying to get his own transportation.

Morgan decided to throw a sushi party at her house and invited all of her friends. Dorothy arrived late but left early to spend time with Cooper, which left her friends peeved.

A little later, Morgan rushed to Dorothy's home after receiving a text message. There, a tearful Dorothy told her friend that she and Cooper had broken up.

Dorothy said Cooper is her first real boyfriend and she felt like her "life is over," but Morgan reassured her that she's going to be fine.
