Rapper Tyga has filed for sole custody of his 11-year-old son, King Cairo Stevenson, whom he shares with ex-Blac Chyna. Tyga submitted the request in Los Angeles Superior Court, seeking both legal and physical custody of their son. According to court documents, he also proposed that Chyna be granted weekend visitation with King Cairo. However, he demanded that she ask for written permission if she wishes to take their son out of California. The former couple, who began dating in 2011 and got engaged before splitting in 2014, have been engaged in a custody dispute for several months. Chyna also shares a 6-year-old daughter, Dream, with her ex-fiancé, Rob Kardashian. The matter remains under legal consideration, and representatives for Tyga and Blac Chyna have yet to comment on the situation.
