She just wrapped up her California Dreams tour, and newly-single singer Katy Perry was spotted arriving back into the States via LAX Airport in Los Angeles on Monday evening (January 23).

The 27-year-old pulled her sweatshirt's hood over her blue locks as she did her best to make a low-key pass through the metro terminal en route to an awaiting car.

The sighting comes after Miss Perry stirred up plenty of chatter during her tour closing show in the Philippines over the weekend thanks to a moment in which she pulled 21-year-old model Ivan Dorschner for an onstage smooch.

While a local newspaper called the Philippine Star made the Perry/Dorschner moment sound R-rated, Katy - who recently split from husband Russell Brand - said it was an innocent part of her act.

Of the stage antics, she tweeted, "Btw, I have *kissed* 1 boy, picked randomly out of the audience, on the cheek as a part of my show for all 125 tour dates. Simmer down now."
