She only missed one city, she'll be in it more next week as they seem to have aired a lot of the Edinburgh auditions (seems to have been the best city this year).
Nicole missed a day of auditions too so she'll disappear at some point (with guest judge Mel B standing in).
She has been a bit quieter so far, although these auditions were filmed in the middle of her marriage problems, so she might be more like her usual self later in the series. She was probably sober when filming the auditions which might explain it! I know in the past she's often enjoyed a tipple before/during the show!
