When she stepped out on Saturday night, Miley Cyrus dazzled in a coral silk chiffon Jenny Packham gown and what looked like a very special accessory – the diamond sparkler she had already revealed on Twitter.

“I am sooo obsessed with @jennahipp nail foundations!” Cyrus, 19, wrote Thursday in a posting meant to show off her manicure but sure couldn’t disguise that ring on her left hand.

The sizable rock has generated talk that she and Liam Hemsworth are taking their relationship to the next level and getting engaged. But, are they?

Cyrus went to Twitter again on Monday to clear things up.

“I’m not engaged,” she writes. “I’ve worn this same ring on this finger since November! People just wanna find something to (talk) about! It’s a topaz people!

Indeed, the ring was very much in evidence Saturday night when Cyrus and her Hunger Games beau, 22, attended Muhammad Ali’s Celebrity Fight Night XVVIII in Phoenix together.

The two have been dating on-and-off since they were first spotted kissing in 2009. They also already share a dog.

Back in 2009, Cyrus told Seventeen about Hemsworth, whom she first met on set of The Last Song, “I’ve never gotten along with someone so well.”
