Trace Cyrus and Brenda Song are engaged!

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! the 22-year-old former Metro Song rocker announced on Twitter.

The 23-year-old Social Network actress Brenda Song sparked rumors this morning when she was seen out shopping wearing what appeared to be an engagement ring, E! reports.The Twitter announcement comes as quite a surprise considering Song and Cyrus have been tight-lipped about their one-year relationship. 

Baby rumors sparked in August when a source confirmed to E! that Song was pregnant. Song's mother, however, told Star last month that her daughter is definitely not carrying a child. Pregnant or not, the happy couple is getting married!

@TraceCyrus can't wait for Brenda to be a Cyrus :) couldn't be more excited about my 'sister in law to be' yay :), Miley Cyrus replied in a tweet to her brother.

No wedding date has been announced.
