The mother-of-one wowed in a floor-length black gown by Elie Saab, which showed off her incredible post-baby body.
Tamara attended the De Grisogono party at the 67th annual Cannes Film Festival on Tuesday evening (20 May), where she walked the black carpet with her very dapper husband Jay Rutland.
It was a very glamorous affair with other guests including Rosie Huntington-Whiteley, Paris Hilton, Rosario Dawson, Amber Heard and Sharon Stone.
Tamara and Jay arrived in Cannes this week with nine-week-old daughter Sophia, who was born on St. Patrick's Day. Tamara has been loving every second of motherhood, sharing cute pictures of her little one with fans. She said of Sophia this week: "We don't remember life without you."
As well as accompanying her parents to glam Cannes, little Sophia has also been in Marrakech, where Tamara filmed a campaign for her Show Beauty range last month.
