The 35-year-old model and TV personality was all smiles after attending the Royal Court Theatre to see Khandan with gal pal Preeya Kalidas.
Brook's theatre-going style? A white summer dress, tan suede ankle boots, pale denim jacket and a bit of designer arm candy.
The sun-kissed wavy tresses, barely-there makeup and gold hoop earrings completed her summer siren style.
Could she be more smiley? Clearly, Kelly's exotic holiday with fiance David McIntosh has put her in a good mood - and perhaps she was filling Preeya in on all those wedding plans...
Kelly posted the following photos on Instagram after her night of theatre-going, wining and dining with her friends in Blighty.
This pic had the caption: "Post Theatre Thespie Dinner after @Preeyakalidas fine performance at the RoyalCourt #Khandan #Play #NewWorks"
