He knows if you've been naughty.

Reprising his role as a very sexy Santa Claus for the second year, model and actor Brock O'Hurn is back to sleigh a new Christmas commercial for Icelandic Glacial's sparking water—and this time he's brought three hot man elves!

O'Hurn's sweaty St. Nick is thirsty for more than milk and cookies, but the tree-trimming housewife he visits in the ad is just too much woman for him to handle.

Icelandic Glacial drew attention last year for a viral ad in which the Instagram hunk distracts both female and male office workers.

The bottled spring water company launched an LGBT-inclusive ad campaign earlier this year toasting personal authenticity in the face of adversity and discrimination.

The company also partnered with Cher to donate more than 181,000 bottles to Flint, Michigan residents whose water supply was tainted by lead contamination.

Watch this year's and last year's Icelandic Glacial holiday ads below.
