Lady Gaga's got a brand new look!
The 31-year-old singer ditched her blonde locks for newly-dyed rainbow hair -- just in time to kick off her Joanne world tour.
Gaga first showed off her colorful tresses on Sunday, posting a selfie of her new hue and glittery red lips on Instagram. Then on Tuesday, the singer shared another closer look at her blue and pinkish-red hair. "Late night running through the show in ⏱," she captioned the pic.

The GRAMMY winner's world tour kicks off Aug. 1 in Vancouver, Canada. In preparation for her first show, the "Born This Way" singer shared a clip of herself stretching during rehearsals and wearing new merch.
"12:19am Vancouver still going strong in #JOANNEworldtour rehearsal! Wearing new tour merch 🦏😎," Gaga captioned the Boomerang.

Over the weekend, Gaga was subpoenaed by Dr. Luke's lawyers to set a deposition date for his defamation case against Kesha.
