Los Angeles: Singer Miley Cyrus and actor Liam Hemsworth are reportedly going through a rough patch in their relationship. Amid rumours that the "Wrecking Ball" star and her beau have called off their engagement for the second time, things between the two weren't always smooth, but they are still trying to make their relationship work, reports hollywoodlife.com. "It is not a perfect relationship but it still is a relationship. At the end of the day they are in love with each other but still have a lot of work to do to make things great," a source claimed. "They get into fights but one thing they are making sure to do is to keep their relationship separate from their careers," added the insider. After breaking up in 2013, Cyrus and Hemsworth sparked reconciliation rumours after the former was spotted hanging out again with the actor and wearing the Neil Lane-designed diamond ring he gave her when he proposed to her. However, they were rumoured to be splitting again after Cyrus was seen without the ring in a recent photograph shared on Instagram.
