The starlet - who recently announced her return to TOWIE - joined a host of famous faces at the London-based bash including her BFF Lucy Mecklenburgh, plus co-stars Lauren Pope, Grace Andrews, Georgia Kousoulou and Fran Parman.
Lyds flaunted her figure in an unusual thigh-grazing frock from Miss Selfridge teamed with a fluffy shawl from Monsoon.
The pretty brunette topped her enviable pins with simple black courts by Jimmy Choo, while toting a matching patent clutch (also by Jimmy Choo) in one perfectly-manicured hand.
And the boutique owner went for high glamour on the beauty front, slicking her lips a Hollywood red hue teamed with super-bold brows and flawless skin.
Her eye make-up was pretty impressive too, with a warm brown tone running through her crease and oodles of black liner, plus mega-watt false lashes.
We wonder if she did her own make-up for the event like fellow Essex gal Lauren Goodger?
