After almost nine years together, the High School Musical alum and the Once Upon a Time in Hollywood actor have decided to go their separate ways, multiple outlets report. The celebs first sparked romance rumours in September 2011, about a year after Hudgens' split with Zac Efron. Hudgens and Butler became inseparable, sharing a number of sweet moments together over the years. In recent months, however, it seems as though Hudgens and Butler have been spending time apart. Hudgens has been overseas filming The Princess Switch 2, while Butler is believed to be starting production on Baz Luhrmann's upcoming Elvis Presley biopic. It was announced over the summer that Butler had been cast as Elvis in the film, and Hudgens couldn't have been more excited. Throughout their relationship, Hudgens has regularly posted photos of her and Butler together on social media. However, in recent months, Butler has been noticeably absent from her posts. She last shared a photo of Butler on Instagram in October last year.
