According to an insider, Perry, 31, arrived at Bloom’s Los Angeles home first and then the pair drove to Downey’s Malibu abode together, with the “Teenage Dream” singer in the backseat with Flynn, 5.
“Katy was entertaining Flynn so he wouldn’t get bored,” an eyewitness tells Us Weekly. “It was a long drive and she was talking to him and making him laugh.”
Though the pair attended the birthday party — for Downey’s son Exton, who turned 4 — together, they kept their hands to themselves.
“The birthday party had a Jurassic theme and there was a giant obstacle course and balloon maker,” the source says. “Orlando was really focused on Flynn and walking around the party holding his hand. Katy stayed behind them most of the time and let them do their thing.”
As previously reported by Us Weekly, the twosome are cozying up, but their romance is in its early stages.
“She’s having fun with Orlando,” another source told Us. “I don’t think she’s seeing this as long-term yet. It’s a fun hookup thing right now.”
Perry and Bloom, 39, first sparked dating rumors when they got flirty at a Golden Globes afterparty last month and then grabbed dinner together at West Hollywood’s Sunset Tower Hotel on Wednesday, February 3.
Perry was last linked to fellow singer-songwriter John Mayer; the exes spent time together at West Hollywood’s The Nice Guy on December 31.
