The former TOWIE star is clearly enjoying the festive season, since she's already been seen at the launch of Hogwarts In The Snow, ice skating in faux fur and turning on the Christmas Lights in Loughton, Essex, with pal Billi Mucklow .
And now she's made a start on her Christmas shopping too, by taking her little sister to Roma to the famous Hamleys of London toy shop on Regents Street.
Lydia was pictured having fun with a life size minion from the film Despicable Me 2 in Hamleys on Sunday (1 December) and dressed up for the occasion in a glittery blue pair of trousers and a matching blazer.
She completed her look with a pair of black courts, fresh faced make-up and an elf's hat.
Meanwhile, Roma was just as stylish in a furry green poncho and a hat similar to her older sister's.
The two siblings appeared to have a great time checking out all of the toys and helping to wrap up gifts with the minions.
Lydia even revealed that she was preparing to put up her Christmas tree later that evening and couldn't wait to stick a giant reindeer in the garden too!
After decorating her home, the ex-reality star headed out for a geek-chic themed party with her favourite friends.
Last Christmas, Lydia celebrated the festive season with her boyfriend and former TOWIE cast member, Tom Kilbey.
However, the pair split up earlier this year and have decided to remain friends instead. We wonder if they've got each other any presents?!
