The daughter of Formula One mogul Bernie Ecclestone brought her gorgeous girl Sophia, one, to the star-studded event at the brand's Oxford Street shop on Tuesday night (3 November).
Sophia was dressed for the chilly weather in a furry white coat, tights and little pink shoes. She really is one of the best dressed celebrity babies around, isn't she?!
The mother-and-baby posed for the cameras before joining celebs including Lydia Bright, Stacey Solomon, Claire Sweeney and Michelle Heaton inside the store, which was celebrating the festive season with a special party.
Tamara's husband, Jay Rutland, wasn't present at the event.
The couple married in a lavish ceremony in the South of France in June 2013, and later held another ceremony at Chelsea Town Hall in London. Their daughter Sophia was born in March 2014.
