It’s turned out to be an extra special holiday season for Kirstie Maldonado…

The 22-year-old half-Mexican/part-Spanish singer and her Pentatonix band mates’ holiday album That’s Christmas To Me has ended the year as the year’s best-selling Christmas set.

The album, which reached the one million mark in sales just before Christmas, ends the year with 1.14 million copies sold.

That’s Christmas To Me is also 2014’s best-selling album by a group.

The holiday album slid by 39 percent in total units (131,000 for the week) and by 41 percent in album sales (121,000) — but holds at No. 3 on this week’s Billboard 200 chart.

In all, That’s Christmas To Me has spent six weeks (all consecutive) locked in the top three of the chart, peaking at No. 2 for two weeks.
