Watch Louise Linton’s First Marie Antoinette Moment From 2007 ‘CSI: NY’ Episode (Video)

Actress wife of Treasury Secretary Steven Mnuchin played a French tutor who got guillotined at a costume gala

Louise Linton, the actress wife of U.S. Treasury Secretary Steven Mnuchin who has come under fire this week for her “Let them eat cake”-like online tirade over her designer-tagged Instagram photo, is no stranger to Marie Antoinette moments.

One of the Scottish-born actress’ very first Hollywood roles was in a 2007 episode of “CSI: NY” in which she played a French tutor who meets an untimely end at a charity costume party where she dresses as — you guessed it — Marie Antoinette.

Her character, Simone DeLille, is led to a decidedly not-fake guillotine by her teenage student — played by Shailene Woodley, the future star of the “Divergent” movie series and an Emmy nominee this year for HBO’s “Big Little Lies.”

In her short scenes opening the Season 3 episode, titled “A Daze of Wine and Roaches,” Linton stumbles in her elaborate costume, and says that she’s not feeling well in a notably poor French accent before suffering a rather dramatic death.

Thus launches an investigation that in characteristically twisty “CSI” fashion involves blackmail threats over Simone’s expired visa, rare poisons, embezzlement over an experimental drug program and even roaches with gemstones attached to them.

Linton, a Scottish-born actress who married former Hollywood producer Mnuchin in June, has been excoriated on social media over her Instagram photos tagging the designer outfits she wore while disembarking from a U.S. government plane with her husband. The tags included high-end brands like Hermes, Valentino and Tom Ford.

She then flew into an odd rant on Monday night against one of her online critics that she has since taken down. In addition to talking about how much taxes she and her husband pay and their self-sacrifice, she thanked the woman for her “passive aggressive nasty comment.”

“Have you given more to the economy than me andmy [sic] husband? Either as an individual earner in taxes OR in self sacrifice [sic] to your country? I’m pretty sure we paid more taxes toward our ‘trip’ than you did,” she wrote.
