According  to TMZ- Miley Cyrus has found true love in Patrick Shwarzenegger:

Miley Cyrus and Patrick Shwarzenegger are full-on in love, and have even casually said in front of friends they will get married some day.

Multiple sources connected with Miley and Patrick tells us their relationship is intense. Miley is going out of her way to impress Patrick's mom, Maria Shriver, and it goes beyond dressing conservatively when Miley's around her. The conversations do not resemble what Miley puts out on social media.

The couple has partied hard, and initially people who spent time with them thought it was just a hook-up, but it's proven to be deeper.  

And we're told it's not like one is pushing the other into getting serious. They're both totally into it.
