Kylie Jenner was busted yesterday – flirting on social media with hip-hop star 21 Savage.

It all started last night when the hip-hop star posted a pic of Kylie on Twitter, with hearts. Kylie appeared to like it so much that she started following SAVAGE on Instagram.

That didn’t last long. People started re-posting screenshots of Kylie following the rapper, and Kylie quickly FOLLOWED him.

Please, no one tell TYGA about it . . . the media might say he’s having a BREAKDOWN.

So you in the know on 21 Savage – he’s an American hip-hop recording artist from Atlanta. He is best known for his mixtapes, The Slaughter Tape and Slaughter King, and his extended plays Free Guwop and Savage Mode with Metro Boomin.
