Katy Perry's new single, "Waking Up In Vegas," has some real-life inspiration.
"We decided to get fake married," Katy told PopEater of a wild night with her then-boyfriend. "I was 21. We took all the pictures with the minister, with the fake cake, in the fake chapel and got a fake marriage certificate. We went and bought a wedding dress and a suit at a thrift store, and scanned the pictures and the certificate to my family members, my manager at the time [and] totally freaked the s--- out of them."
"It was the most hilarious, stupid prank I've ever pulled," the pop star, now 24, continued. "I still have the wedding dress and the certificate."
While many regret their trips to Sin City, Katy added that her song isn't about apologizing.
"[It's] basically a song about getting into trouble with your best friend or your boyfriend or your girlfriend – or whoever you're with – and not having any 'I'm sorry for what I did,'" she told the site.
