Adele has several wigs that she has worn on various occasions due to the fact that it takes so long for her to get ready. When giving Anderson Cooper a tour of her house, she took him into her bedroom and showed him some of her wigs strewn on the bed. Adele also told him that she jokingly gives them pet names, revealing two of them to be “June” (after June Carter) and “Jackie” (after Jackie Collins).
Prior to the release of 25, Adele would frequently wear wigs during various television appearances and live shows. In Live at the Royal Albert Hall, she wears a wig.
According to her official forums, Adele wore wigs for much of the North American leg of her Adele Live tour.
