The reality star, 31, joyously sang and danced along during her man's raved-about concert (his first solo appearance in over a year). And when West performed one of his newer songs, "Way Too Cold" (formerly known as "Theraflu"), the rapper serenaded his love directly.

In the instantly famous track, which first leaked back in April and helped confirm the Kardashian-West romance, West raps "I admit I fell in love with Kim."

At another point during the show, West bellowed to the crowd: "If you love someone tonight..hold on real tight!" Kardashian hugged Cheban and then herself jokingly.
