Sydney – Australian “Hunger Games” actor Liam Hemsworth has proposed to “Hannah Montana” girlfriend Miley Cyrus, with the pair tweeting their engagement on Thursday.

“Thank you for all the support. We are both very happy!” said the Melbourne-born Hemsworth, who met the teen star in 2009 while filming “The Last Song” after relocating to the United States to pursue his career.

Cyrus, 19, tweeted: “I’m so happy to be engaged and look forward to a life of happiness with @LiamHemsworth!!!”

“I feel like all my dreams are coming true. Life is beautiful.”

Hemsworth, 22, who is currently shooting “Empire State” in New Orleans, said the ring was “hand-cut around 1880 or 1890 and it’s unique and in its original form”.

“It’s a contemporary design based on vintage aesthetics. The light flashes and sparkles no matter where she moves her hand,” he said.

Cyrus made her name as a teen idol in the “Hannah Montana” TV series but moved to shake-off her squeaky-clean image with raunchy music videos after she quit the show.

Her father, Billy Ray Cyrus, who also starred in “Hannah Montana”, said he was over the moon.

“All I ever hoped for as a Daddy was to see my kids reach their dreams. To find happiness… peace of mind… and someday know… true love,” the “Achy Breaky Heart” crooner said.

Fellow teen idol Demi Lovato, who made her name in “Camp Rock”, added her congratulations, tweeting: “Congrats and happiness to you both. Love you.”
