Binky, who is in the Big Apple with her co-stars for MIC's spin-off series, celebrated her special day with her sister Anna-Louise and their mother Jane for lunch.
Later on, Binky joined her best pals including Louise Thompson, Fran Newman-Young and Mark-Francis Vandelli for a night out - and things got messy!
The brunette certainly let her hair down as she was pictured on the dance floor with Louise, and later sharing a girly kiss with flatmate Fran Newman-Young.
Captioning the snap, Fran said: "Happy birth-boxing-day my troublesome roomie #sugarlips @binkyfelstead."
The night was so good, that Binky ended up losing her phone! Luckily, she found it the day after and was quick to reminisce about the night.
Binky, who turned 24 on 14 June, wrote: "Thank u @LouiseAThompson - I've never been happier to have my phone back! What a glorious night/ I was a nightmare!"
One person who didn't appear to be at the celebrations was Alex Mytton.
Over on the current series of MIC, Binky and Alex have been trying to make a go of their relationship following Alex's confession that he had been unfaithful.
On tonight's show (16 June), which is the last in the series, Binky and Alex are still determined to work things out alone, but mutual friend Spencer Matthews claims that everyone thinks they should split.
