The duo posed separately ahead of the amfAR Gala in Los Angeles on Thursday night. Perry showed up in a powder blue frock with feathered and tool neckline, while Bloom kept it cool in a black suit.
What's interesting is the on-again/off-again couple just walked the red carpet together for the first time last month in Monaco ... so, why not now?
Inside the annual event, which raises money for HIV/AIDS research, Perry and Bloom were clearly showing some PDA amongst fellow celebrities like Carmen Electra, Chris Tucker, Heidi Klum, Rumer Willis, Judd Apatow and more.
The duo, who welcomed their first child in February, recently announced they are expecting baby #2 due sometime next year.
