Earlier in the night, the 24-year-old actress and 28-year-old Emmy winning dancer were seen out at Universal Studios Hollywood Halloween Horror Nights with Derek‘s sister Julianne and actress Lily Collins.
Rumors that the duo were a new couple came about at the end of last month.
“@Derekhough !!!!!!!! #EMMYWINNER I cant express in 140 characters how unbelievably excited+incredibly proud I am of you. You deserve this,” Nina posted on Instagram after Derek won the Emmy last month.
FYI: Nina is wearing a Viscose Lycra Tank from twenty.
