Things are certainly getting serious for "The Voice" couple as the holidays approach.

And right before they hopped on a plane to Music City, Shelton and Stefani were spotted out and about in the Los Angeles area last week.

While the No Doubt frontwoman was shopping for Christmas presents in Van Nuys, her beau was seen hanging out with her dad, Dennis Stefani, at her parents' home in Westlake.
