Nikki Garcia (AKA Bella) looks happy doing the single mom thing ... taking her son to his dance class after getting a restraining order against his famous father.
Nikki was spotted Friday in Napa, CA for the first time since a judge gave her court-ordered protection from "Dancing With the Stars" pro Artem Chigvintsev.
She was smiling as she carried their son, Matteo, in her arms ... and they had matching all-black outfits.
TMZ broke the story ... Nikki beelined it to court this week and got a restraining order against Artem in the wake of his August arrest for domestic violence.
