Despite her new romance and major PDA with Patrick Schwarzenegger, Miley Cyrus might not have been over Liam Hemsworth after all, as she reportedly still keeps in touch with her ex-fiancé.

It has been two years since Cyrus and Hemsworth called off their engagement. According to In Touch (via HollywoodLife.com), the pop star is still in love with 'The Hunger Games" actor and has been calling and texting him nonstop, when Schwarzenegger is not around.

"They text constantly and even talk on the phone when she's not paranoid Patrick will catch her," a source revealed. "She's also been sending Liam long flirtatious emails reminiscing about their time together."

The publication also reported that Hemsworth even came over to Cyrus' place, and "the passion was still there."

Liam Hemsworth is currently in Australia, and the "We Can't Stop" singer reportedly keeps telling her friends that "she can't wait to see him when he returns. If he wanted to get back together, she would dump Patrick in a heartbeat."

Meanwhile, the growing romance between Miley Cyrus and Patrick Schwarzenegger is apparently tearing the latter's divorced parents further apart, as an insider close to the Schwarzeneggers told HollywoodLife.com:

"Miley and Patrick's relationship is causing a lot of tension in his family. It's creating a fissure in Arnold and Maria's already tense relationship -- and it's affecting all of their children."

While Maria Shriver does not approve of her son dating Cyrus, Arnold Schwarzenegger reportedly likes the young couple together. "Arnold loves that Patrick is dating Miley," the insider continued. "He's been showing her off around Ketchum [Idaho] to all his friends."

"Arnold loves being in the spotlight and is really enjoying all the attention Patrick's relationship with Miley is getting," the insider added. "He's proud of Patrick for dating such a sought after girl like Miley. He compares it to dating Madonna at the peak of her fame."
