Model and singer Amber Rose disapproves of rap star Tyga's romance with her ex-boyfriend Kanye West's teenage sister-in-law, because he should be at home with his baby.

In a new radio interview, Rose blasts Tyga for leaving her good friend Blac Chyna for 17-year-old Kylie Jenner.

She says, "That's ridiculous. 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."
