After a couple of breakups in 2010, Miley Cyrus and Liam Hemsworth seem to be going strong now -- but a new report suggests that the 'Can't Be Tamed' singer is worried about losing the 'Hunger Games' star to fame.

According to Hollywood Life, the 19-year-old wants to solidify her relationship with her 22-year-old actor boyfriend before his career takes off, as many believe it will once the Suzanne Collins adaptation hits theaters in March. "She wants to establish as much of a foundation in their relationship as possible," a source says.

However, the worry doesn't come from insecurity. The insider explains that "Liam has always had fan girls," so Miley isn't worried about him cheating or going astray. It seems that the extra focus on their relationship simply has to do with having as much special time together before the spotlight is on the pop singer and her Australian beau, much like the case of 'Twilight' stars Robert Pattinson and Kristen Stewart.

At the end of the day, Miley is just trying to preserve what she has with her man. "People forget how young she is," the insider adds. "She’s allowed to be crazy in love."
