The TOWIE star kept all eyes on her while attending an event at the Sanctum Soho Hotel in central London on Wednesday night (18 September).
Lucy wore her eye-catching chic green suit with a simple black vest top and black statement necklace, teamed with gold sandals.
Last night's event was to celebrate the launch of Made In Chelsea star Cheska Hull's new PR company, Big Smoke, so as you'd expect, plenty of the MIC cast were out in force too to support her.
For Lucy, it was a big night out before she heads off to glamorous Las Vegas with the rest of her TOWIE co-stars to film two one-hour specials for the new series.
Lucy's no stranger to the US, recently returning from a business trip to LA where she met with a film producer about a possible Hollywood movie role and had meetings about bringing her Results With Lucy website to the States.
The 22-year-old founded Results With Lucy earlier this year. It provides Lucy's guidance and tips on healthy eating and exercise.
The star has been hard at work this month filming new cooking and workout videos for the website, which will include for the first time dance, boxing, hooping classes and yoga.
