Taking to his Instagram handle, Nick posted a picture in which PeeCee, dressed in green, can be seen sitting on his lap as he plants a kiss on her cheek.
They are surrounded by their pets, with a huge, decked Christmas tree and lots of gifts in the backdrop.
Nick added the caption, “Merry Christmas everyone. From our family to yours.”
Fans flooded the post with love-filled comments.
“Relationship goals,” a social media user wrote.
“Cutest family,” another added.
The much-in-love couple, who are often in a long-distance relationship due to their busy work schedules, got married in December 2018.
