'Rupaul's Drag Race' Finalist Adore Delano Joins Britney Spears on Stage at her 'Piece of Me' Tour in Las Vegas [Watch]

Gentlemen start your engines and may the best woman win.

Those are words that Adore Delano will be hearing on Monday night's finale of Rupaul's Drag Race when she faces off against Bianca Del Rio and Courtney Act to see who will become America's Next Drag Superstar.

To take the pressures of the crown off Delano's mind, she went to America's playground, otherwise known as Las Vegas, this weekend to relax and see the one and only Britney Spears.

Not only did Adore get to live out her dream of meeting Ms. Spears, but she also got called on stage during a performance of "Freakshow." Mid-song the "Work Bitch" singer attached a leash to Adore's neck and playfully forced the drag queen to crawl down the catwalk on all fours.

To commemorate the night, Delano posted the following picture with the caption "YAY!! @britneyspears is #teamadore thanks for letting me on stage last night! <3"

This past week, the Queen of Pop extended her "Pieces of Me" show through next February, making the diehard fans who haven't had a chance to make it out to Vegas extremely happy. Tickets to the new shows went on sale this past Friday, and the first round of seats for the August and September shows have already sold out.

The songstress may also be looking to extend her contract with Planet Hollywood through December of 2016.
