Josh countered during his opening routine by fake singing to Justin's 2015 hit song What Do You Mean? as host LL Cool J and color commentator Chrissy Teigen looked on.

Christina was supported by her five-year-old daughter Violet who joined her at rehearsal.

She had Violet with ex-husband The-Dream but they split shortly after Christina gave birth.
