Just 35 seconds into the new clip from Mariah Carey, we’ve seen four versions of her. There’s Mariah the singer, cavorting on the couch in front of the photographers, there’s Mariah the superstar, stepping out of the limo into the arms of her awaiting fans, Mariah the chauffeur (which must be confusing when it comes to working out who’s driving) and there’s Mariah the shopper, weighted down by all those glamorous shopping bags. Two minutes in, there have been two more Mariahs – the Mariah with the hairdryer blowing hot air all over the Mariah cavorting on the couch and Mariah the rapper, writhing up against the wall-full of Mariah photographs. All these Mariahs, all this ‘Obsession’ – our heads are spinning! As always, she looks immaculate throughout.
