The former I'm A Celebrity and CBB star turned 33 this week and let her hair down on Friday night (19 September) with her good pals.
Nicola looked stunning in a knock 'em-dead LBD which showed off her famous curves and the figure that brought her huge success as a glamour model.
Teaming the dress with animal-print heels and matching clutch, Nicola was all smiles despite her recent relationship heartbreak.
Sexy Aisleyne flashed the flesh in a scarlet bra top with skin-tight pencil skirt, while Maria looked cute in leather shorts, laced-up boots and a black Trilby... We like, ladies!
We bet ALL eyes were on them as they partied the night away in Brentwood, before heading to favourite hotspot Sugar Hut.
After posting a selfie of herself hugging the birthday girl, Maria tweeted: "My girls bday. Love her @NicolaMcLean." To which Nicola replied "love you babe".
Before heading out, Nicola told fans she was planning to get "drunkkkkk".
The mum-of-two was recently devastated after the breakdown of her marriage to retired footballer Tom Williams.
At the time, she told Reveal: "I've known my marriage has been over for months, but I've been fighting it. I'm the lowest I've ever felt.
"Everyone sees me as a strong, hard-faced bitch, when actually I'm just an insecure girl who wants her marriage to work."
She has since accused Tom of having a mistress, and even tried to move on by sharing a kiss with TOWIE hunk Maria Falcone.
We hope you had an amazing birthday, Nicola!
