Is Blac Chyna already pregnant with her third child? Rumor has it, the 28-year-old model and her fiance Rob Kardashian may be expecting another baby after welcoming their first bundle of joy together, Dream Renee Kardashian.

Dream may soon be a big sister as Blac is determined to have another child with Rob despite his sisters' plan to tear them apart. An insider tells InTouch, "[Blac]'s told friends she always to have two Kardashian babies. She and Rob break up, move out, get back together and have amazing make-up sex. Chyna could easily be pregnant again already."

Unfortunately, it won't be easy for the couple to have another child if Rob's family has a say. According to another source, Kim Kardashian, Kourtney Kardashian and Khloe Kardashian are joining forces with Kris Jenner for an intervention as Blac is psychologically abusive to Rob.

"They believe his fiancee, Blac Chyna, has been psychologically abusive to Rob," the second source says, "At first they thought she was a positive influence, but they know believe she is killing him. So after Rob's emergency trip to the hospital, his family hatched a plan to get rid of Chyna once and for all."

Blac is also a mother to a four-year-old son, King Cairo, from her previous relationship with Tyga.
