The reality TV star and boutique owner, 24, oozed sophistication - as usual! - when she enjoyed a family trip to London's Natural History Museum's seasonal ice rink.
Wearing green and blue tartan trousers, Lydia kept warm in HUGE fluffy mittens and a navy blue tie coat from her own boutique, Bella Sorella.
And, naturally, Lydia's auburn locks and smoky eyes were done immaculately. Cue a serious girl crush!
Lydia was clearly thrilled to be having fun with her family, including fellow TOWIE-star mum Debbie.
The pair are famously close and are often seen on screen discussing Lydia's turbulent relationship with on-off boyfriend James 'Arg' Argent.
Also enjoying the festive fun, was Lydia's new foster sister Keira.
Although Lydia was careful to maintain her new sister's privacy and keep her face off camera, she did share a picture of the family with Keira in it.
Lydia wrote: "Our little family. So happy we got blessed with a new little angel this Xmas my new foster sister on the end. #FosterFamily #Happy just missing @f_bright1998."
She also affectionally teased her new sibling's first ever skating experience, calling her "#BambiOnIce".
Earlier this year, Lydia told us how her mum Debbie has fostered over 250 kids during a 22-year period.
Nurturing Debbie has also taken troubled Arg under her wing in the past.
He is reportedly spending Christmas in The Priory to overcome his issues with partying, alcohol and drugs.
