The Fomula One heiress uploaded this gorgeous photo to Instagram on Monday night (19 May), showing little Sophia giggling for the camera.
All together now: awwwwww!
Tamara added the caption: "Nine weeks old today. We don't remember life before you."
The brunette and husband Jay Rutland became parents for the first time on St. Patrick's Day, when Tamara gave birth to Sophia, who weighed 6lbs 9oz.
"Proudest day of our lives," she said at the time. "Never felt love like this."
Little Sophia may only be nine weeks old, but already she's quite the jet-setter. Last month, she joined her parents in Marrakech, where Tamara was working on her Show Beauty range. And today, she arrived in Cannes with her mum and dad for the Cannes Film Festival.
