Russell Brand is officially back on the scene following his split from wife Katy Perry.

The Arthur star was spotted at hot spot Lexington Social House in Hollywood Saturday night with a male friend…and he looked anything but broken-hearted.

Brand, who arrived at the restaurant/nightclub around 12:30 a.m. with his buddy, had nothing but love for a few females who shouted out his ex's name as he walked into the establishment.

"Katy Perry!," they yelled, probably in an attempt to get a rise out of Brand, but the 36-year old funnyman simply smiled and went inside.

Meanwhile, Perry is also moving on.

The "Firework" singer sealed her first show post-breakup with a kiss, planting a big wet one on a shirtless male fan's cheek during her performance in Jakarta, Indonesia last week.
