Like many rifts between two men in the past, the common denominator is usually a woman. The same is here. Bella Hadid is the one in question. She is a supermodel and is 21 years old. Her mother is Yolanda Hadid and she has a famous sister too, Gigi Hadid who is also a model and a year older than Bella. In 2015, Hadid and The Weekend began a relationship. They appeared together in his video and other red carpet affairs.
Later there were rumors that Drake and Bella had had a relationship earlier. This caused the storm to brew between The Weekend and Drake. Both men attend the same events and they go to the same places which sometimes escalate the rift between the two.
