Miley Cyrus seems to have fallen hard for her new boyfriend, Patrick Schwarzenegger. The "Bangrez" singer has reportedly never loved any of her previous boyfriends as much as she loves Arnold Schwarzenegger's son.

"I have seen Miley with Liam (Hemsworth) and other boyfriends but honestly I have never seen her look as loved up as this," a source revealed to E Online. "This is more than just a fling, they look like they are falling in love with one another," the source added.

Since breaking up with Liam in 2013, this is the first time that Cyrus has gone public with her relationship. She has been spotted with Patrick on various occasions already. On Nov. 13 at the USC football game, Miley was seen kissing Patrick. The duo has also gone on a slew of dinner dates. They first hooked up at this year's Halloween celebrations.

Much recently, Miley spent some time with Patrick's family during the annual tree lighting ceremony in L.A. on Nov. 15. The couple was seen cuddling up as the 100-foot-tall Christmas tree illuminated. The tree was decked with more than 15,000 lights and 10,000 adornments. The couple also witnessed a spectacular exhibit of fireworks, which marked the end of the ceremony, according to Hollywood Life.

This is not the first time that Miley has spent time with Patrick's family. She has previously attended the Q&A session of Patrick's mother, Maria Shriver, for the film "Still Alice." Shriver is the producer of the film. The singer has also met Patrick's older sister, Katherine Schwarzenegger.

If Patrick is introducing Miley to his family, then things are reportedly getting serious between them. However, it remains to be seen how long the relationship will last.

Miley dated Liam for almost four years. They met on the sets of "The Last Song" in 2009. The couple went public with their relationship at the premiere of their film. In June 2012, the two announced their engagement but called it quits in 2013 for unknown reasons.

Since then, the estranged couple reportedly continues to stay friends. Liam is currently single, though he has been linked to Nina Dobrev in the past.
