Katy Perry Made People Feel Like They Time-Traveled on Her Birthday
Katy Perry is, in her words, "such a birthday party girl". That day gives her an excuse to throw a massive party. The singer admits she gets so much joy from watching her friends have the most fun and make long-lasting memories. For her 32nd birthday, she hosted a Halloween-themed 1950s sock hop that made guests feel like they'd taken a time machine.
