The 35-year-old was lapping up the sunshine in Thailand, where she is currently enjoying a getaway, and the snapshot also showed a stunning ocean view.
The image showed the Fast And Furious star in the nude while sitting cross-legged in the lotus position on a grassy lawn.
The actress shared a photo on her Instagram page in which she was completely naked.
The couple, who apparently met in January, flew to Milan by private jet leaving London in the early hours of Thursday morning before Cara appeared on the catwalk for Fendi.
The inseparable pair weren't apart for long though as Michelle even hung out backstage with Cara at the show, while she had her make-up done.
