It looks like Katy Perry is creating quite a roar among the leading Democratic contenders in the 2016 presidential race.

On Tuesday, the 29-year-old pop star shared an epic picture taken with Vice President Joe Biden on Instagram. In the photo, the two are smiling while posing in the White House.

"Brought my pink pony to the White House to holler @VP Joe Biden. #wheninwashington," wrote the "Fireworks" singer in the photo caption, adding, "p.s. He made me call my 93 year old grandma to thank her for my baby blue eyes! What a Q-T."

According to CNN, the VP and his granddaughter are fans of Perry's music, which is why he invited her to meet them while she is in town on her Prismatic World Tour, said an official from Biden's office.

Perry also stopped to take a tourist picture with the Washington Monument during her stop in Washington D.C. before her performance Wednesday night at the Verizon Center, reports E! News.

"DC! Tonight's gonna be on point, every pun intended!#THEPRISMATICWORLDTOUR photo by @ronysphotobooth," wrote Perry.

The "Dark Horse" singer, who has always been a vocal advocate for President Barack Obama, also expressed her support for another member of the Democratic party when she caught up with former Secretary of State Hillary Clinton at her book signing for her new memoir, "Hard Choices."

"I told hillaryclinton that I would write her a 'theme' song if she needs it," the singer wrote as a caption on Instagram while at Clinton's book signing last Thursday in Los Angeles.

However, Clinton seems to already have a favorite Perry song in mind.

"@katyperry Well that's not a Hard Choice. You already did! Keep letting us hear you Roar," Clinton tweeted in response Sunday, referring to the singer's smash hit "Roar."
