The Formula 1 heiress proudly showed off her figure in a fitted black skirt and unusual midriff-baring top while out at dinner with husband Jay Rutland on Tuesday (13 May).
Tamara welcomed her first child, Sophia, on 17 March.
Clearly motherhood suits the brunette star, who recently gushed: "Our beautiful little angel has completed me."
"Becoming a mum to Sophia the greatest gift ever feel so blessed," she said. "A very special journey has started for the three of us never been happier."
Tamara, 29, recently marked Sophia's birth by having an 'S' tattooed on her hand. She also has a tattoo on her neck in honour of her husband, reading: "JR, I love you."
The star - whose dad is Formula 1 boss Bernie Ecclestone - married stockbroker Jay in a lavish French Riviera ceremony last year attended by celebrity friends and family. They held a second smaller ceremony in London shortly afterwards.
