Pixie Lott transformed into Marilyn Monroe as she shared behind-the-scenes snaps from her West End show The singer, 35, swapped her pop roots for a turn as the Hollywood icon in a new production titled Who Killed Marilyn? at the Emerald TheatreThe new production, written by Sharleen Cooper Cohen and directed by Philip Wm. McKinley, sets out to examine the woman behind the legend, revisiting Monroe’s life and her death, which was officially ruled a probable suicide from a barbiturate overdose.But in his review, Patrick noted that despite shining a light on Marilyn’s demise, the play has ‘all the drama of a Wikipedia entry’.He wrote: ‘For all the plot’s febrile fiction, Lott makes a good fist of her role in Philip Wm. McKinley’s zestless production, despite overusing her famously breathy, rising intonation famous from films such as Some Like It Hot.’She is also over-dependent on flirtatiously running hands down her thighs while bending legs and winking.’Such moves only reinforce the Marilyn myth and never really get behind the mask.’Even so, Lott toils to the end of the 140-minute pot boiler, talking us through Marilyn’s lively celebrity sex life as if from the grave.’And her impersonation does become increasingly emotionally charged – culminating in a psychological epiphany with her shrink.’Regardless of the reaction, Pixie was a dead ringer for the legendary Hollywood star with a bleached blonde bob and her signature red lip.
