As a Singer

Kay Cook began singing when she was very young. After she set up her YouTube channel, it helped reach a bigger audience. On June 8, 2018, she released the official lyric video of her debut single ‘Thoughts’ through her channel. She has since put out four more tracks, ‘Love Me’ (2018), ‘Favourite Drug’ (2019), ‘Upgrade’ (2019), and ‘1952’ (2019). Her songs are also available on Spotify, iTunes, and Apple Music.



Cook was in a relationship with a youth named Olivier Mascarade. They parted ways in June 2018. It was Mascarade that started the rumour that Zach Herron, a member of the five-piece boy band Why Don’t We, had coaxed her to drink excessive alcohol and took advantage of her. This prompted a response from Cook. In a fan DM, she stated the allegations were not true, adding “it’s all false it’s kind of sad what olivier is doing to get attention”. Mascarade also accused Cook of cheating on him with Herron, but she indicated that this was a lie as well. Her song ‘Upgrade’ was apparently based on their relationship, which ended when he broke her heart.

In June 2017, Kay Cook posted a cover of ‘Something Different’ by Why Don’t We on her YouTube channel. She clearly has been a fan of the band for a while. By June 2018, she and Herron were studying at the same school. They met, and in July, began a relationship, attending the prom together in June 2019. In July, their families travelled to Cancún, Mexico together, where Cook gave a live performance.


On August 4, 2019, Cook took to Instagram to claim that her boyfriend had cheated on her and they had split. Although she did not mention Herron by his name, many of their fans already knew that they were dating. According to Cook, the incident took place in early 2019, when he was visiting Hawaii. Herron responded on Twitter, “don’t believe everything you hear, seriously hurt.” He also announced that he would be taking a break and deactivated his Instagram account.


Daniel Seavey, another member of Why Don’t We, came to his friend’s defence in a since-deleted tweet, “Don’t believe everything you hear!! There’s lots of people in the world out for their own gain just be careful who you trust.” Cook also turned her Instagram account inactive and left social media for a period. In a video shared by a fan, Herron stated at one of the meet and greets that he was incapable of putting “someone through that”.
