What’s appropriate? Seems like Kanye’s ex and does not approve of the relationship Kanye’s wife, Kim Kardashian’s youngest Kardashian sister, Kylie Jenner, has with rapper Tyga.

In a recent radio interview, Amber Rose was quoted as saying “She’s a baby, she needs to go to bed at 7 o’clock and relax. He should be ashamed of himself. For sure... He has a beautiful woman and a baby and left that for a 16-year-old who just turned 17.”

Besides the age difference between the two (and the whole statutory issue), there may be another reason why Amber’s coming at Tyga’s neck [II]: she’s very close friends with the mother of Tyga’s child, former stripper Blac Chyna.

No way Amber’s words wouldn’t get back to the 1st family of reality TV. Today, big sister Khloe Kardashian came to Kylie’s rescue on Twitter, throwing her own shots Amber’s way. Khloe made mention of Amber's past of stripping at the age of 15, stating that people in glass houses shouldn't throw stones.

Of course, the ladies went back and forth for a while after that… Read the entire exchange here.
