If Orlando Bloom isn't Katy Perry's boyfriend -- officially -- he's definitely the most supportive friend we've ever seen.

First, there was her pre-GRAMMYs party that the actor showed up at, and on Wednesday, Bloom attended a Hillary Clinton fundraising concert at Radio City Music Hall in New York City where Perry was performing.

The 31-year-old pop star performed hits like "Fireworks" and "Unconditional" and, according to Variety, praised Clinton, saying, "I'm not voting for her because she's a woman. I'm voting for her because she's the right person for the job."

Elton John and Andra Day also performed during the rally, while Bill Clinton -- whom John called the "future first mate" -- and daughter Chelsea spoke. Afterwards, Perry posted an Instagram in a "Hillary Clinton Is a Badass" T-shirt and captioned it, "Nuff said."

Bloom and Petty may have left the event separately -- she spent 15 minutes taking selfies and signing autographs with fans -- but reunited for dinner at Carbone later that night. It was their second date in as many days, following Tuesday's dinner at The Polo Bar, one of the toughest tables to get in NYC.

While the duo previously tried to keep their relationship under wraps, they've certainly seemed more comfortable showcasing some PDA lately. Last week, the singer and the 39-year-old Lord of the Rings star were spotted holding hands during a vacation to Hawaii.

"They looked very loved up and really into each other," a source told ET. "They were comfortable letting everyone see them as a couple -- lots of PDA and hand-holding."
