Liam Hemsworth, Miley Cyrus engaged again?

LOS ANGELES, Jan. 19 (UPI) -- Miley Cyrus and ex-fiancé Liam Hemsworth have sparked new engagement rumors.

The 23-year-old American singer sent fans into a frenzy by sharing a photo of herself wearing a diamond ring Monday on Instagram. The sparkler appeared to be the 3.5-carat engagement ring Hemsworth gave her in 2012.

"I look like a [expletive] strawberry #looklikemy[expletive]momdressedmethisam #prettysureihadthissamelookat6," the star captioned the snapshot.

Cyrus was spotted with a U-Haul truck outside Hemsworth's home over the weekend, leading some to believe she is moving in. Sources told TMZ the singer moved her things into the 26-year-old Australian actor's Malibu house over the past week.

Cyrus and Hemsworth were previously together four years, but called off their engagement in 2013. The couple reunited for New Year's Eve and were seen at the Falls Music Festival in Byron Bay, Australia, days later.

"Miley never got over Liam," a source subsequently told People magazine. "Despite them constantly fighting before the split, Miley always said Liam is the love of her life. There were so many things that she loved about their relationship."

Hemsworth's brother, Chris Hemsworth, dodged questions about the rumored couple during an interview Tuesday on the Kyle & Jackie O Show. The 32-year-old actor, who was recently named a global ambassador for Tourism Australia, said he didn't know if the engagement is back on.
