Controversial Aussie actor Matthew Newton and Transformers star Rachael Taylor are officially engaged, after a passionate one-year relationship.

According to a well-known source, the Underbelly star popped the question to his blonde girlfriend earlier on in the year, to which Taylor immediately said ‘yes’.

“Quite a while ago now, almost two months maybe, but they are really happy,” the unnamed source said.

“She said yes straight away. The couple are known to be wild about each other and are rarely apart.

“They just understand each other. They are a really unique couple,”

It is believed that only friends and family knew about the announcement, but it should explode onto the media in the next few weeks as the pair try to cut a deal with a weekly magazine to feature the story.

It is reported that $50,000 is the leading bid, but the title of that magazine has not been revealed.

The pair has made headlines in the past year, mostly Newton, the only son of TV legend Bert.

Last year they were spotted in LA getting each other’s names tattooed on their wrists and made headlines again when a hotel room Newton was staying in was severely damaged.

It was booked under Taylor’s credit card, but Newton denied any allegations.

The engagement of the couple is a sign Newton has moved on from his previous dramas with Aussie actress Brook Satchwell, to whom he reportedly abused.
