Lupita Nyongo's $150K Oscars dress has been stolen from her Hollywood hotel room, according to TMZ.
Lupita wore the custom Calvin Klein gown that featured 6,000 pearls to the 87th annual awards ceremony on Sunday.
It is understood the outfit was taken out of her room at The London hotel in West Hollywood.
She told police it went missing between 8am and 9pm on Tuesday while she was out, TMZ reports.
Authorities are now searching CCTV footage for answers.
On Wednesday the actress shared a timelapse video of her pre-Oscars prep which shows her with her style team in her hotel room getting her glammed up before the big event.
The morning after the Oscars, Lupita shared a snap of her beautiful accessories she'd worn for the the night and captioned:
'That was cool! #Oscars 2015 #DiamondsAndPearls'
Laid out on top of her frock were some stunning Chopard jewels and satin Nicholas Kirkwood heels alongside a silver box clutch.
Lupita returned to the Oscars after winning the Academy Award for Best Supporting Actress last year for her work in 12 Years A Slave.
'This year the pressure's off,' Lupita told E! host Ryan Seacrest during the E! red carpet show.
