Although Kylie Jenner and Tyga have yet to really let us see any public displays of affection, it's become common knowledge that the two are boo'd up thanks to Kanye West's Breakfast Club interview and T-Raww's not-so-subtle Instagram posts of Kylizzle. 

Amber Rose has been outspoken with her thoughts on Tyga and Kylie's relationship, in defense of her friend and Tyga's ex-girl Blac Chyna. Blac Chyna, meanwhile, has been doing some sub-Instagramming directed towards Kylie. 

Last night Chyna Instagrammed a picture where her lips were grossly enlarged, which comes on the heels of the #KylieJennerChallenge trending across the net. Although she didn't include the hashtag, it's pretty obvious. Later, Chyna threw some more shade when she posted a picture of her ass(ets) with the caption "Permanently," seemingly in response to Kylie's photo of herself driving what is rumored to be Tyga's truck with the caption "Currently."
