Miley Cyrus proved she is her beau's number one fan by sporting a shirt with Liam Hemsworth's name emblazoned on the back.

The Wrecking Ball singer and The Hunger Games actor have remained tight-lipped on their rekindled romance, but on Sunday (19Jun16), Miley seemed to confirm their on-again relationship on Instagram.

The 23-year-old posted a selfie with a mirror behind her, with the name "Hemsworth" printed across the back of her shirt.

She didn't offer context for the snap, but rather captioned the photo with three cats with heart eyes emojis.

Miley and Liam met while filming The Last Song together in 2009, and got engaged in 2012. However, they split in 2013, before finding their way back to each other last December (15).

The pop star has been sporting the custom engagement ring Liam gave her ever since they reunited, and the pair has been photographed together several times, but have yet to confirm their official status.

Most recently, they were spotted holding hands during a date night in New York City last week (ends19Jun16).

Earlier this year (16), Liam dismissed rumors he was engaged again and insisted the pair was not heading down the aisle anytime soon.

"I just find it's easier to not talk about my personal life because usually I say the wrong thing, so it ends up just complicating things more," he told Entertainment Tonight last month (May16). "So, I feel like it's better not to talk about it."

However, when Miley and Liam do decide to wed they already have a volunteer lined up to officiate the ceremony - Miley's dad, Billy Ray Cyrus.

He recently told breakfast show Today, "They know if they need a preacher they've found one!"
