Trace Cyrus proposes to Brenda Song

Miley Cyrus' half-brother Trace has asked his actress girlfriend Brenda Song to marry him.

Rocker Trace Cyrus broke the news to fans on his Twitter.com blog on Friday (14Oct11).

He writes, "I am very excited to say, last week I asked my girlfriend Brenda Song to marry me and she said YES! We are both very excited to be engaged!"

And the 22 year old isn't the only one looking forward to settling down with The Social Network star.

Miley tweets, "can't wait for Brenda to be a Cyrus :) couldn't be more excited about my 'sister in law to be' yay :)"

News of the couple's engagement emerges just weeks after Brenda Song's mother denied reports the actress, 23, was expecting a baby with Trace Cyrus.
