A source tells PEOPLE that Orlando Bloom attended Perry's party.
"It's really sweet," a source inside the event says. "The party is for music producers and artists only but Orlando showed up a bit later and they're together."
Held at Los Angeles' Cicada restaurant, the art deco-themed party welcomed past and present Grammy nominees together with up-and-coming acts, producers and songwriters to celebrate Monday's Grammy awards. Guests like Ariana Grande and Beck (Perry's tablemates) enjoyed a champagne reception and danced to top 40 hits performed by an orchestra.

Perry, who snuggled up to Grande and posed with Sia, wore a black and gold, see-through mesh corset with black leggings and pumps. Her hair was pulled tight into long french braids and she accessorized with Pamela Love Five Spike earrings with white topaz in yellow gold.
"In some way, I'm trying to start the Met Ball of music," Perry told the New York Times before the event.

Perry, 31, and Bloom, 39, have been spending a lot of time getting to know each other in recent weeks – and it seems their relationship is continuing to heat up.
"Orlando and Katy are spending more and more time together," a source told PEOPLE. "They are introducing each other to friends [and] they look very happy together.
Prior to The Creators party, the pair took their relationship to the next level when the pop singer joined Bloom and his son (with ex Miranda Kerr) Flynn, 5, at a kids birthday party at Robert Downey Jr.'s house.
"They were laughing, playing music and joking around with Flynn," and insider told PEOPLE of the February outing. "They stayed at the party for hours. Katy looked very comfortable at the kids party. She seemed very happy to spend the day with Orlando."
Perry and Bloom first ignited romance rumors at the Golden Globes last month, where they were seen chatting for half an hour and even shared a drink.
