Miley Cyrus is reportedly dating Patrick Schwarzenegger.

The ‘Wrecking Ball’ hitmaker is said to have been “casually” romancing the 20-year-old son of Arnold Schwarzenegger but insiders insisted to E! News that they are “not officially together.”

The “good friends” were seen together with a group of around six people at the Universal Studios Hollywood’s Halloween Horror Nights on Thursday (30.10.14) and the following morning they headed to Patrick’s Los Angeles apartment to prepare for Halloween festivities.

This isn’t the first time the pair are believed to have dated, as in 2011 they went on a number of outings together, but Miley, 21, went on to reconcile with now-former fiance Liam Hemsworth.

That same year, Patrick voiced his crush on the former ‘Hannah Montana’ star.

He said: “My eye, though, is set on Miley.”

In August, Miley admitted she still loves her ex-fiance Liam, whom she dated on and off for four years until September 2013.

Speaking about their friendship, she said: “I love Liam, Liam loves me.”

Liam was also overheard gushing about his ex-lover – whom he started dating while filming ‘The Last Song’ in 2009 – during dinner with friends in Italy in July and told pals they will always be best friends.

A source said at the time: “Liam kept raving about how amazing she was, how much they clicked and understood everything about each other.”
