Things are certainly heating up between the two A-listers.

Fireworks definitely seem to be sparking between Katy Perry and her rumored beau, Orlando Bloom.

The 31-year-old hosted The Creators Party, a pre-GRAMMYs bash presented by Spotify, on Saturday, and the Pirates of the Caribbean actor was just one of the many A-listers who was spotted at Los Angeles' Cicada restaurant.

Perry showed up to the party solo, posing for pictures on the red carpet in a black and gold sheer lace Dolce & Gabbana corset and high-waisted trousers, Christian Louboutin mesh pointy pumps, Nina Ricci choker and gold Pamela Love five-spike earrings. She sported French-braided pigtails, much like the ones Kim and Khloe Kardashian have been rocking as of late.

Inside the venue, the rumored couple -- who have been sparking romance rumors over the past two months -- were seated at a table with Ariana Grande and Beck, People reports. Guests dined on a four-course gourmet dinner, which included menu items like shaved cauliflower, parmesan reggiano, braised beef, Ragu lobster cockles and Italian rainbow and pignoli cookies.

Perry later took to social media as well, thanking the streaming service for holding the event.

"Had the most fun being authentic with my peers," she tweeted. "Thank u @Spotify for understanding the community that we are creating & holding the space."

There was one person notably missing from the star-studded soiree, however: Taylor Swift.

Despite their presumed feud, Perry took the high road and sent an invite to the "Bad Blood" singer, though she told The New York Times she wasn't sure if Swift would be able to make it due to her schedule.
