Tamara, 30, and husband Jay Rutland, 31, were no doubt bursting with pride, bringing along their seven-month-old girl for the special occasion at Scott's exclusive restaurant in Mayfair, London.
Tamara looked stunning in a black sleeveless dress but it was Sophia who melted our hearts by looking snug as a bug in a fluffy cream hooded coat and later in a baby pink dress.
Earlier, Tamara posted an adorable Instagram snap of herself posing with her daughter, captioning it: "On way to grandad's birthday dinner."
Later on, she then showed how Sophia and her grandfather were bonding by sharing another photo of the tot making a grab for Bernie's glasses!
Tamara joked: "The glasses thief strikes again!" Too cute.
Baby Sophia may only be a few months old, but she's already a globetrotter just like her mummy.
At the end of July, Tamara was pictured in St Tropez with her little girl after jetting there with her mum, Slavica, and they've recently just returned from a sunshine break in Ibiza - where Tamara showed off a very toned post-pregnancy bod in a bikini.
It's fair to say Tamara and Sophia made the prettiest picture when they posed for a selfie on board their yacht.
Don't suppose you're after a nanny by any chance, Tamara?
