Kourtney Kardashian appeared to pick sides in the ongoing feud between sister Kylie Jenner and Selena Gomez - and it's not what you'd expect.
The 43-year-old reality TV star opted for a tune by Selena, 30, to help promote her latest product.
The choice is sure to raise eyebrows within the famous family and fans were quick to question whether it meant Kourt was siding with the singer over her younger sister.
