A YOUTUBE star kicked off her 21st birthday celebrations with a McFlurry-themed party.

Saffron Barker, who has amassed more than 420 million views on her YouTube channel, held a small gathering of friends and family at a private location in Uckfield.

The Strictley Come Dancing star's birthday party featured a visit from a McFlurry van, an ice cream inspired birthday cake, beach club decorations and party anthems supplied by DJ Suat.

The McDonald’s Airstream, a customised food truck trailer, was converted into a bespoke McFlurry van.

The celebrations were in aid of both Saffron and McFlurry – with both turning 21 this month.

The Brighton-based YouTuber’s birthday is on July 24.

As part of the celebrations, McDonald’s is giving the public the chance to win a party, just like Saffron’s, with three hours of free McFlurry’s, a DJ set and party stylist.

The competition is free to enter, with entries made via the McDonald’s website. Entries close at 11.59pm on July 26.

Two winners will be chosen at random to win the prize, with both having to be available to host an event on August 14, 15, 21 or 22.

A McFlurry consists of McDonald's vanilla-flavoured ice cream in a cup, often served with a chocolate topping.

Starting from just 79p, the McFlurry’s topping options include Galaxy Chocolate, Oreo and Maltesers.
