American singer/actress Miley Cyrus is rumoured to be dating Patrick Schwarzenegger.

According to a report in E! News, the We Can't Stop singer and the 21-year-old son of Arnold Schwarzenegger and Maria Shriver have been spending a lot of time together.

However, multiple sources told the website that the two are casually dating, and aren't "officially together."

Cyrus and Patrick were allegedly spotted together on 30 October at Universal Studios Hollywood's Halloween Horror Nights with a small group of friends. The next day the duo were spotted hanging out at his Los Angeles apartment as well.

Patrick has previously talked about the former Disney star.

"My eye, though, is set on Miley," he told Details magazine in 2011.

Cyrus has been linked to a number of A-list men including, Twilight star Kellan Lutz, Canadian singer Justin Bieber, since splitting from Australian actor Liam Hemsworth.

The Hunger Games star and Cyrus met on the set of Nicholas Sparks film The Last Song, in 2009. In 2012, Hemsworth proposed to Cyrus with a 3.5-carat Neil Lane diamond ring.

The couple made their last public appearance together at the premiere of his film Paranoia at the DGA Theater in Los Angeles, before Hemsworth officially announced his split from the Wrecking Ball singer.

Previously, in an interview with Elle magazine, Cyrus had confessed that she thought she would die without her Disney career and Hemsworth.

"When I went through a really intense breakup — you know, I was engaged — and when I was with him [Hemsworth] or when I was on Disney, the thing that gave me the most anxiety was not knowing what to do with myself when Disney wasn't there to carry me anymore or if I didn't have him.

"And now I'm free of both of those things, and I'm fine. Like, I lay in bed at night by myself and I'm totally okay, and that's so much stronger than the person three years ago, who would have thought they would have died if they didn't have a boyfriend," Cyrus said.
