After debuting her new single “Problem” — in Minnie Mouse ears, no less! — at the Radio Disney Music Awards in Los Angeles, CA last night (April 26), Ariana Grande made her way to Palm Springs, CA to perform at the 25 Year Anniversary of the White Party Palm Springs, the largest gay dance music festival in the world!

Ariana went retro in a white fringed crop top and mini skirt with the white go-go boots she rocked at the White House Easter Egg Roll this past Monday. With a thick white headband and her hair pulled back into a swishing high pony, she put on an amazing show for a crowd at the Palm Springs Convention Center who was loving every second of it — including another performance of “Problem” featuring Iggy Azalea, which is available on iTunes at midnight tonight!
