Ariana was seen rocking a pink bob wig, as well as some cool threads, while enjoying the Las Vegas event with Tom Sandoval.
Tom also got into the spirit with a tie-dyed tee and some fly moves.
Ariana somehow managed to look even cooler in this very festival-appropriate photo taken by Tom.
This isn't the first time we've seen Ariana look pretty in pink. She previously channeled her inner unicorn at her 30th birthday party in Season 4. She also briefly dyed her hair pink last October in support of breast cancer awareness. She showed off her rosy locks at the Desert Trip music festival in Indio, California.
It appears as though Ariana has been all about new 'dos as of late. She debuted her new lob in May.
And then Ariana unleashed her fierce, new look in a recent glam photo shoot for 360 Magazine.
Check out some more pretty pictures of Ariana, below.
