Katy Perry
kissed a new guy ... and he definitely liked it!

The singer hit the stage in Jakarta, Indonesia today, her first public appearance since Russell Brand filed for divorce back in December.

Despite the split, Katy appeared to be having a great time during the show -- where, at one point, she pulled a shirtless local on stage, playfully rubbed his chest and gave him a big kiss.

He looks pretty happy, doesn't he?

Upon her arrival in the country, Katy tweeted "I'm SO EXCITED to FINALLY be in INDONESIA! U guys have waited forever ."
