The 18-year-old reality star started dating Tyga in 2014 and the pair had a relationship since then.
However, following several reconciliation after splits in the past, the couple has apparently called time on their romance once and for all.
Kylie and Tyga’s relationship hit headlines earlier this year when her half brother Rob Kardashian started dating the mother of Tyga’s son, Blac Chyna.
Blac and Rob are now engaged and expecting their first child together.
Neither Kylie nor Tyga have commented on the split rumours.
