American singer Selena Gomez, who had once collaborated with South Korean girl band BLACKPINK is now dating record producer and songwriter Benny Blanco, a BTS ARMY. He recently launched his cookbook Open Wide on The Tonight Show With Jimmy Fallon and baked a BTS-themed purple cake for the occasion. 

BTS is a South Korean boy band comprising seven members - RM, Jimin, Jin, Suga, Jungkook, V, and J-hope. For those unversed, purple is a symbol of love for the BTS ARMY since V said "Do you know what purple means? Purple is the last colour of all the rainbow colours, so it means I will trust and love you for a long time." This gave birth to the phrase "I Purple You".
