Twenty hours after news broke that Miley Cyrus and Liam Hemsworth are getting married, the singer was spotted leaving Los Angeles on Thursday to reportedly jet off to visit her fiancé on the Louisiana set of his new movie, "Empire State."

It's not the first public outing for Miley since she announced she and her boyfriend of three years plan to marry. On Wednesday, she was spotted in Malibu wearing her new bling at a photo shoot and walking around the beachside town with her mom, Tish, according to the Mirror.

Sources told Radar Online that her parents are hoping she and Liam will wait a bit to get married, but other sources tell UsMagazine.com that despite her young age, she's ready to make some very adult moves in her life.

"She's very mature! She's 19 going on 40, so she is ready for [marriage]. Liam likes her wild side, but Miley's also mature and supportive. They're both ready for this," the source said, adding that as for wedding plans, "Nothing yet [is planned], but she's starting to work on it!"

Meanwhile, insiders tell People.com that "she's pretty independent already." The source added, "They're just so happy she's found someone who makes her so happy. Billy Ray loves Liam. He's happy his daughter has found the right guy. The whole family loves Liam."

Hemsworth popped the question on May 31 after three years of dating. He asked with a 3.5-carat Neil Lane sparkler.

Miley is taking some time out of recording her next album to visit Hemsworth. According to sources, that album will reflect her more mature state of mind. Recording with the likes of Pharrell and Hit-Boy, the insider shared, "We are watching a young girl turn into a young woman."
