Los Angeles - Tyga is happy for Blac Chyna and Rob Kardashian.
The rapper's former fiancée recently got engaged to her boyfriend of three months and while Tyga and Blac have had an acrimonious relationship since their split, he insisted he only wants her and their son King Cairo, three, to be happy.
Tyga, 26, tweeted:
Blac, 27, was previously close friends with Kim Kardashian West but fell out with the family after Tyga started dating their younger sister Kylie Jenner, 18 and the Kardashian and Jenner clan are reportedly less than thrilled about the engagement.
A source said: "No one in his family is jumping up and down with excitement. They have made a united decision as a family to not comment on social media yet about Rob's engagement. But the news is not shocking, and not totally unexpected."
