The Celebrity Big Brother housemate swapped her usual slinky, flirty frocks in favour of an of-the-shoulder dress with intricate lace detailing.
Lauren told Twitter followers she was going for a "Hollywood glam" feel, teaming her floor-sweeping gown with golden blonde ringlets and sultry make-up.
She was at the National Reality Awards, held at the Porchester in Bayswater, London, to present a prize… and catch up with some of her old CBB housemates.
In a photo posted to Instagram, she can be seen cuddling up to Gogglebox's George Gilbey, who had been among the string of celeb pals wishing her happy birthday last week.
Lauren was out of the CBB house just in time to celebrate her big day on 19 September with a girly lunch at Sheesh Chigwell and a relaxing day.
Lauren later tweeted: "Thank you everyone for my birthday wishes yesterday! Was a lovely chilled birthday. New start today for another new year ahead."
As part of that new start, it seems the ex-TOWIE star is turning her attentions to her nutrition, embarking on a new diet.
After enjoying an Indian takeaway watching X Factor at the weekend, she posted a photo of her lunch yesterday, comprising of boiled eggs and grapefruit, telling fans it was part of a new healthy eating regime.
