She's been counting down her 30th birthday for weeks now and with the big day just less than 24 hours away, Casey has kicked things off in style.
Any excuse for a glass of bubbly, right?!
Enjoying an afternoon filled with champers, mini sandwiches and cakes galore, Casey shared a photo of herself and her two pals as they toasted the Celebrity Big Brother star turning a year older.
Captioning her photo, Casey said: "Lovely afternoon tea for early birthday celebrations with two of my longest and bestest friends @missjacquiadams @mporterfield33 love you both."
Earlier this morning (1 October), Casey was feeling reflective ahead of her birthday tomorrow.
Taking to Twitter, she tweeted: "Today is the last day in my twenties! Better make it a gooden! Twenties you've given me a lot of fun. Tomorrow is the start of a new chapter."
Making sure to see in her 30s in style, Casey has planned a big bash for her birthday and we've no doubt the Essex girl is bound to pull out all the stops for her party.
With her birthday high on her agenda for the last few months, Casey has whipped herself into shape to ensure she is looking her best for the special occasion.
Back in July, Casey embarked on a get-fit mission - involving plenty of exercise and a healthy diet - to tone herself up in time for her 30th.
As well as training hard, Casey also underwent a breast reduction to reduce her chest from a GG to an EE cup. After feeling a little self-conscious about her boobs beforehand, Casey is loving her new assets and certainly hasn't been shy when it comes to showing them off.
Earlier this week, Casey was spotted giving us all a glimpse of her smaller boobs in a very revealing white catsuit.
We reckon she's never looked better!
