Here are some new pictures of Katy Perry during her first post-split appearance on Friday. Katy’s date to the event in Las Vegas was Markus Molinari, a jewelry designer, and one of the hosts of the charity event.

While it was her first appearance since splitting from husband Russell Brand, Katy was visibly more “quiet” than she typically is at these types of events.

Back in the United States to see friends and support a charity, Katy Perry strolled down a red carpet for the first time since her split with Russell Brand.

The singer rocked her blue hair and donned a cocktail dress with metal studs at the overnight Friday event for Givelove.org, which provides sustainable low-income solutions Haiti earthquake victims.

Markus Molinari, a designer for J. Molinari Jewelry, told PEOPLE that Perry was doing “amazing” and she was in town to support his cause because “that’s what friends do.”

At the event at the 1 OAK club in the Mirage Hotel, Perry hung out in a VIP booth and watched her pal Ferras perform.

“She was really tame,” a source said. “She was really just drinking a few drinks and chilling with her friends.”

Earlier, Perry went to Stack restaurant, joining a table of 18 and dining on steak, seafood and red wine and listening to another performance by Ferras on the piano. Perry was seen clapping, cheering and swinging a napkin the air.

The singer is back from doing shows in the Philippines and Indonesia.

Hopefully Katy gets back on the horse soon! After hearing that Russell is out hooking up with girls all over the country, I want her to move on and find someone new!

PS: She looks great!

Also at the event were the Hilton sisters, Paris and Nicky, as well as David Arquette and his girlfriend Christina.

Nicky Hilton, the quieter Hilton sister, has split from longtime boyfriend David Katzenberg. David is the son of DreamWorks honcho Jeffrey Katzenberg. Despite the fact that their families had hoped the pair would marry, they were unable to work things out.

One friend told us, “They broke up quietly after four years together. The main reason was that they have been busy with their work schedules, and it has made it difficult to spend time together. Nicky has been back and forth traveling overseas a lot with her business. She has recently been in Asia promoting her jewelry line, and David is starting a new production company. Their schedules never seemed to match.”

The friend added, “There is no scandal or any third person — they remain close friends, they have been friends since they were teenagers.”

Despite the split, sources say Nicky and David talk regularly and have been tweeting one another.

Jeffrey, a creator of MTV series “The Hard Times of RJ Berger,” has set up KatzSmith Productions with Seth Grahame-Smith. He recently told Collider that the two are working on another MTV-scripted comedy and “trying to cross over into feature-land.”

“Right now, we’re just getting off the ground,” he said. “We have a comedy spec that we’re going out with soon. Seth is working on his next book. There’s a lot of stuff in the air right now, so we’ll see how things land and where they fall.”

Reps for Hilton and Katzenberg declined to comment.
