Rob Kardashian has joked he's now an "orphan" after dropping his family to be with girlfriend Blac Chyna.

The pair's relationship has caused controversy from the beginning, as Blac has a three-year-old son with Tyga, who is dating Rob's half-sister Kylie Jenner. Blac also previously threw shade at Tyga, 26, and 18-year-old Kylie's relationship due to the age gap between the pair.

According to reports, when Rob's older sister Khloe Kardashian found out about the romance she kicked him out of her house, where he had been living for the past few years.

He is now believed to be living with Blac.

Rob shared a meme on his Instagram page on Wednesday which read: "When the p**sy good but your family don't like her so you drop your family and become an orphan."

He left a caption off the quote but adding some laughing until crying emojis.

Rob's joke comes just weeks after Khloe posted a heartfelt message saying she "misses" her sibling. It has also been claimed that his mother Kris Jenner, who is said to be one of the biggest opponents of Rob's new romance, is demanding that he try and sort things out with his sisters.

"Kris demanded a face-to-face with Rob," an insider told Britain's Closer magazine. "She told Rob that if he wants to be with Blac Chyna, he should stop using her as a weapon against their family and try to sort things out with his sisters, who are up in arms.

"Blac Chyna told Kris that she doesn't want to upset their family and is prepared to make up with the girls. Rob doesn't know what his next move is at the moment - he's trying to bury his head in the sand."

Kylie has yet to comment on the situation, but Tyga briefly spoke out during an appearance on Khloe's chat show, Kocktails with Khloe, saying: “Everybody deserves to be happy."
