You Won't Believe Where Katy Perry Celebrated Her 31st Birthday

— -- It doesn't take much to make Katy Perry's day.

The "Roar" singer, who turned 31 years old on Sunday, continued the celebration on Tuesday with a dinner with a bunch of friends at Olive Garden.

"When you could go anywhere for your bday dinner but you're so OG that you go to OG with all your OG's," Perry captioned an Instagram photo of the group, along with the hashtag, "#thosebreadstickstho."

No word on what she ordered.
