Ariana Biermann got it from her mama, Kim Zolciak, because the reality TV personality was snappin' away in Alaska -- sharing her fun couple's vacay with her man, Hudson Mcleroy.

Staying warm on the mountaintops, the two lovebirds held on tight to each other with the serene snow as the backdrop!

Ariana and Hudson also hit the slopes for some skiing, climbed into a helicopter for a scenic ride, and were even treated to the Northern Lights!!!
