The heiress was on her way to the exclusive de Grisogono Fatale in Cannes party at the prestigious film festival.
Wearing a glamorous black dress, with red lipstick and gorgeous diamond earrings, the mum-of-one looked stunning.
Joining Tamara was husband Jay Rutland, who looked dashing in a tuxedo.
The star also shared a photo of her hubby, alongside the caption: "My handsome date #cannes."
This comes a day after Tamara shared a photo of her adorable baby daughter Sophia, giggling for the camera.
