Pop star Miley Cyrus has reportedly been making late night phone calls to ex-boyfriend, actor Liam Hemsworth.
The 20-year-old has been trying to prove that she has moved on, but a source close to her says it's not easy for her to restrain her pain, reports hollywoodlife.com.
"She's still very hung up on him but she's not writing him letters begging for him back. The worst she's done is call him late at night when she gets emotional," said the source.
"She's in a lot of pain still over this breakup so she's had a few weak moments but she always regrets it the next day. The random hook-ups happen when she's been partying. She's trying to get over Liam and her coping skills are not the greatest so she's partying the pain away," the source added.
Cyrus and Hemsworth dated for four years before going separate ways in September.
