With Colin Mathura-Jeffree about to throw another epic birthday party, we check out how the rich and famous celebrate getting another year older.
Never let it be said that Colin Mathura-Jeffree doesn't know how to throw a party.
And with his 45th birthday rolling around this year, he's decided there's no better time to go full Studio 54 with hundreds of friends and family.
In what promises to be one of the most memorable parties of the year, Mathura-Jeffree says "it's time to have a wild Studio 54 style party for the movers and shakers that are the map of my life".
And if it's anything like his previous big birthday bashes, this year's lucky guests are in for quite the treat.
Mathura-Jeffree held an exquisite masquerade ball at Auckland harbourside venue The Wharf for his 40th birthday.
With hundreds of guests in attendance, the party was covered extensively in several women’s magazines and featured on the short-lived reality TV show, The Ridges.
Boh Runga sang Happy Birthday, the birthday boy's initials were beamed on to the nearby Harbour Bridge and the 500 guests were a veritable who's who of Auckland society.
A few years later, Mathura-Jeffree went for a Bollywood birthday party theme, in what proved to be another memorable soiree, this time at the St James on Queen Street.
Having just competed on MediaWorks' Dancing With The Stars reboot at the time, Mathura-Jeffree said his birthday do also doubled as the "unofficial after-party of DWTS". (It apparently became a bit of a Bachelorette reunion, too.)
So what about Kiwi A-Listers who live Stateside? Surely they must have birthday celebrations on a grand scale as well, right?
Well, yes and no.
Lorde was lucky enough to be thrown the party of all parties when she turned 20 in New York last November.
Her bestie, one Taylor Swift, organised an event positively bursting with major celebrities (think Lena Dunham, Karlie Kloss, Aziz Ansari and Mae Whitman), with Lorde proclaiming it "the best birthday party I've ever had".
Thanking Swift on Instagram, the Kiwi singer wrote: "Here's to our three magic years of best friendship and more moments like this squished between angels."
(Lorde, of course, celebrates her 21st birthday this year, however we doubt a yardie will be found anywhere.)
But it's not all impressive parties in swanky New York restaurants when you're a big deal in the US. Especially when you're a mum to young children.
Actress Anna Paquin, who lives in Los Angeles when she's not working on location, enjoyed a low-key birthday last month, which seemed to consist largely of cards and gifts celebrating her potty mouth.
Although it looks like her actor husband Stephen Moyer was declaring his undying love for her in this cheeky birthday card, so Paquin is still winning when it comes to birthday celebrations.
Meanwhile, Honor Carter has been making the most of celebrating her birthday while living in France with her rugby-playing husband and their two sons.
The Carters have enjoyed several exquisite European holidays and attended numerous glamorous events while based in Paris, so it makes sense that the former hockey international chose to spend her birthday weekend in Champagne this year.
And it was, she says, "the most amazing weekend ever".
Max Key's 21st birthday last year made plenty of headlines, given it was held at the plush Parnell mansion belonging to his parents, then-Prime Minister John and Bronagh.
Key Jr decided on a Superheroes and Villains theme for his big birthday (hence the Batman costume), however his parents chose to ignore that dress code.
Just prior to the big day, Max Key sent guests a Facebook invitation, promising to provide "alcohol and sh*t yarns".
A further Facebook post reiterated that a "f**k-load of alcohol" was being provided free of charge, proving that some 21st birthday traditions are still going strong.
And it looks like it was a label-tastic birthday celebration for ZM breakfast host Megan Sellers last month.
Her fiance, singer Andrew Papas, not only bought Sellers a pair of Gucci earrings, he also took the time to make her a few Chanel birthday cakes.
Sounds like a keeper there!
Finally we have Sellers' ZM colleague, PJ Harding of Jase & PJ fame.
High on life at her 27th birthday party over the weekend, Harding was inspired to break out an impromptu rap for her assembled guests.
With lines like "we're gonna have some money on the bar tonight, nobody gonna get in a fight,” it's probably no surprise that Harding later told radio viewers that she "hadn't practised" the rap ahead of time.
But here it is in all its glory anyway.
