Country star GWEN SEBASTIAN had a Christmas to remember after getting engaged.

The Hard Rain singer took to her Twitter.com page to share her happy news after her drummer boyfriend Louis Newman popped the question over the festive season.

The blonde posted a photo of her sparkling engagement ring, along with the caption, "I'm officially off the market. I love you Louis."

It has been an eventful 2012 for Sebastian - she was invited to tour with Blake Shelton after she was kicked off U.S. TV talent show The Voice in March (12), and she also joined him onstage at the Academy of Country Music Awards in April (12).
