Katy Perry could literally go anywhere and do anything for her birthday, but all she wanted was "good times, great salad."

And where do you go for that? The Olive Garden, of course. The "Dark Horse" singer rang in her 31st birthday with all of her "OG's" and took them to an OG where they no doubt indulged on an endless supply of soup, salad and breadsticks.

Katy posted this pic to her Instagram with the caption, "When you could go anywhere for your bday dinner but you're so OG that you go to OG with all your OG's."

Katy and her crew looked they had a great time at the Italian chain, which isn't too much of a surprise because "when you're here, you're family."

The singer, who just wrapped up her Prismatic World Tour, hit the Olive Garden one day after she showed her support for presidential hopeful Hillary Clinton.

Katy performed "Firework" at an Iowa Rally and took over Clinton's Instagram account, showing off her Hillary manicure and, of course, some selfies.

The pop star and Clinton don't just have close ties -- they also have close birthdays. Clinton celebrated her birthday the day after Katy on Oct. 26, and KP gave her a special shout-out on Instagram, voicing her support for the potential 2016 Democratic nominee.

"So, I stand with her for my daughters and their daughters, and beyond what time gives me," Katy captioned a section of the photo. "Get informed, get involved and become empowered!"
