Kesha needs a break, y'all!

The singer jetted off to Mexico, on Sunday, in the wildest kaftan we've ever seen -- accessorized with knee-high lace-up gladiator sandals with rainbow-colored pompoms and pink, yellow and blue hair to match!

Kesha's kimono got heads turning at LAX as she said a little prayer before getting on her flight. A source tells X17, she's off to enjoy some sun, fun and relaxation south of the border, after her legal battle with Dr. Luke has taken a toll on her mental health. "She just needs a break. She needed to get away from all the lawyers and courtrooms and stress. She's doing just fine, though; her fans have been so supportive, she knows she's in the right."

Enjoy the trip, Kesh ... you deserve it!
