Clark County in Nevada officially declared 5 November as Britney Day and the 'Toxic' hitmaker had one massive celebration.
Greeted by thousands of cheering crowds at the LINQ Promenade, 32-year-old Britney made a rather spectacular entrance by appearing behind an array of feathers following a performance from Las Vegas showgirls.
But what was the best bit about the celebration?
Anyone named Britney – with any spelling of the name – was invited to join her at bash, and they also bagged tickets to her Las Vegas residency show, 'Britney: Piece of Me'.
Last month, it was announced that the popstar would be honoured with her own holiday, and we bet she was counting down the days!
Given it was a pretty special and mega day, Britney was also presented with the key to the Las Vegas Strip.
And following her celebration, Britney announced new show dates for her Las Vegas show. The pop icon has added a mammoth 36 additional dates to her show between March and September 2015.
Britney kicked off her residency on 27 December last year, and she was initially contracted to perform 50 shows a year in 2014 and 2015.
It's no surprise that Britney has received such a special tribute with her very own day. Aside from her successful 'Piece of Me' residency, the singer has enjoyed more than 15 years in the music industry.
