The purchase is expected to be completed in the third quarter of the fiscal year 2021 and sees Coty deepen its collaboration with the celebrity Kardashian-Jenner family.

In January, Coty, acquired a 51 percent stake in Kylie Jenner's cosmetics brand. Jenner is Kardashian's half-sister.

The pair have built a beauty empire on the back of the success of the hit reality TV show "Keeping Up with the Kardashians," which first aired in 2007.
