She's just returned from a spiritual quest where she 'ate, prayed and climbed a volcano'.
But on Sunday it was back to work as usual for Katy Perry as performed at the Singapore Formula One Grand Prix on the Marina Bay City Circuit.
The singer seemed in high spirits as she watched the likes of Jensen Button and Lewis Hamilton competing before taking to the stage.

Curvy Katy made the most of her best assets in a low-cut flattering black, blue and white patterned dress.
The I Kissed A Girl singer, who has recently had her hair dyed both blue and purple, had gone back to her roots, sporting a simple, sleek dark brown bob.
Katy seemed in high spirits as she happily posed for the cameras but she seemed most excited as she flashed the peace sign standing in front of one of the cars in the pit.

The musical star performed later drawing the three days of racing to a close.
And Katy appeared to be dressed as a pit girl for the final concert and was dressed in a revealed outfit before ripping off her skirt to stand in just a leotard.
She took to the stage after Sebastian Vettel was crowned at the podium following his win.
