Amber Rose Calls Kim A "Whore"

Amber Rose don't stop until she's at war with ALL of the Kardashian-Jenner sisters -- she just yanked Kim Kardashian into what started out as a jab at Kylie Jenner ... by calling her a "whore."

Amber started the shade-slinging by going on a radio show and ripping Tyga for dating 17-year-old Kylie Jenner. The back story, of course, is Tyga's ex Blac Chyna is Amber's BFF.

Then Khloe Kardashian stood up for her kid sis with a tweet reminding everyone Amber's admitted she was a "stripper since I was 15 years old.”

Now ... Amber's fired back with a gem of a meme -- a pic of Kanye West with the text ... "When ur sister in law calls out ur ex for being a stripper ... But ur wife has a sex tape."

And that was Amber's 2nd salvo blowing up Kim -- earlier she tweeted Khloe, "I'll be that lil whore to support my family like ur older sister is a whore 2 support hers." 

Even more H.S. drama -- Wiz Khalifa (Amber's ex) just started following Khloe on Twitter ...

seemingly siding with her & Kylie -- while Reggie Bush (Kim's ex) is now following Amber.
