Hey, Miley! Is that an engagement ring on your finger? Aren’t you a little too young — 17 years old —to be moving so fast with your boyfriend Liam Hemsworth?

Miley Cyrus was spotted yesterday by photogs in Hollywood wearing a very suspicious sparkly piece of jewelry on the fourth finger of her left hand — and tongues are already wagging. Could she be engaged to Aussie co-star Liam Hemsworth, 19,whom she met just last June on the set of her new film The Last Song, a coming-of-age movie about a rebellious teen? Hmm! Sounds familiar! She has just returned from Australia, where she reportedly met Liam’s family — could that have been a prelude to an engagement?

But this wouldn’t be the first time Miley’s made a dramatic move that’s highly age-inappropriate.

1. At her 17th birthday party in NYC on Nov 18, she dressed as Julia Roberts’ high-class hooker in Pretty Woman
2. Just weeks before that at the Teen Choice Awards on Aug. 9, she pole-danced provocatively on an ice-cream cart wearing next -to -nothing.
3. And even before that, she set off a huge controversy when she posed topless just wrapped in a sheet for famed lenswoman ,Annie Leibovitz, inside Vanity Fair magazine when she was just 15 years- old. Later that year, pics spread all over the Internet of her lifting up her shirt to show her bra, and lying suggestively on a bed. She confessed in the VF interview that her favorite show at the time was Sex and the City, not exactly teen viewing material.

Hard to believe that you’d walk down the aisle so young , but stranger things have happened!
