President Obama thanked Katy Perry for her political support of the Affordable Care Act in a big way on Sunday night. During the 2013 MTV VMAs the leader of the free world singled out the pop star on Twitter, thanking her for retweeting a message about the health care initiative to her more than 41 million followers.

The controversial health care law, which will take effect on Oct. 1, continues to face opposition from Republicans, most recently from Texas junior Sen. Ted Cruz.

Earlier Sunday night, after performing her new single “Roar” at the much-talked-about awards ceremony, Perry shared two messages the president had authored, both of which urged followers to sign up for health care coverage beginning on Oct. 1. In response, the president tweeted back at Perry, writing, “Thanks for spreading the word. #ROAR

“Happy to do my part, PREZ!” Perry wrote back.

She later added, “YO what a day! #ROAR-ing @ the #VMAs, Tweeting w/POTUS, & now happy to announce U chose #DARKHORSE FT @therealjuicyj to come out Sept 17th!”

Perry's newest hit single has come under fire for its similarity to Sara Bareilles' "Brave," although the pop diva has continued to promote it at full force. And it’s not the first time the unlikely allies have bonded over social media. In tow with Beyoncé and Jay-Z, Perry has proven one of the president’s most ardent celebrity supporters. The “Teenage Dream” singer has performed at several of the Obama/Biden rallies and even used her outrageous fashion to try to shore up support.

Last October, Perry performed at a rally in Las Vegas, Nev., where she advocated for the president in a skin-tight latex dress printed to look like an election ballot. Across Perry’s chest were printed the words, “President of the United States” in large capital letters, and underneath were check boxes for Obama and Romney, the former of which had been filled in.

Perry has also gotten creative by dying her hair blue, and sporting an Obama-themed manicure at an earlier rally before the election. Her strong support for the commander-in-chief has earned her some perks, including getting a shout-out for both her and her 91-year-old grandmother on her birthday.

Perry has made no secret of her political stance in the past, staunchly defending free health care and describing herself as a gay activist. In a 2011 interview with Rolling Stone, Perry said that politics were a new passion of hers. It just feels like the thing running our country is a bank, money," she said. "I know it sounds like an intense viewpoint, but I'm only slowly but surely getting the wool taken off my eyes. When I was a kid, I asked questions about my faith. Now I'm asking questions about the world."

“I think we are largely in desperate need of revolutionary change in the way our mind-set is,” she added. “Our priority is fame, and people's wellness is way low. I say this knowing full well that I'm a part of the problem. I'm playing the game, though I am trying to reroute. Anyway, not to get all politically divulging and introspective, but the fact that America doesn't have free health care drives me f---ing absolutely crazy, and is so wrong."
