Christina Aguilera hit something of a bum note with her much-hyped Whitney Houston tribute at today's American Music Awards - and one former musical rival stole the show with an instantly viral reaction shot.
Aguilera took to the stage to perform a medley of songs from Houston's film The Bodyguard, which turns 25 this year. She opened with arguably the late diva's signature song, I Will Always Love You - and despite her powerhouse vocals, proved that Houston's iconic performance is hard for anybody to live up to.
Cameras cut to fellow pop star Pink in the audience, her eyes locked on Christina, her expression - what? Pain? Concentration? Sadness? Horror? Who knows:
The cameras cut to Pink again later in the song, and her expression had by then softened - she was shown smiling and applauding. After the performance, she was quick to clear up any confusion about her feelings towards her old Lady Marmalade singing partner.
