Miley Cyrus and Patrick Schwarzenegger, the son of Arnold Schwarzenegger and Maria Shriver, have reportedly started dating.

Miley Cyrus, Patrick Schwarzenegger Dating?

Cyrus and Schwarzenegger, both 21, have sparked dating rumors as of late. The two were pictured exiting Schwarzenegger’s apartment over the weekend prior to hitting up a Halloween party. Cyrus also joined the budding actor at Universal Haunted Hayride on Thursday.

While one insider said that the two are causally dating, another said they "are not officially together," to E! News, adding that they "are good friends."

Back in 2011, Cyrus briefly dated Schwarzenegger before moving on with The Hunger Games star Liam Hemsworth. Their brief relationship came after Schwarzenegger admitted, "My eye, though, is set on Miley,” to Details magazine.

“Miley is so over bad boys,” a source had told the National Enquirer at the time. “[She] is looking to rope Patrick into a full fledged romance."

“Billy Ray and Tish think Patrick is the kind of stable guy Miley needs,” the sourced continued. “Arnold and Maria worry that Miley might lure Patrick into the Hollywood party scene.”

Neither Cyrus nor Schwarzenegger have addressed the speculation.
