Now, a few months on and seems both Lili and Cole would like to remind everyone that they are still a happy couple.
The 22-year-old actress revealed to Coveteur her plans for Halloween.
"I think I'm leaning in towards a character for Halloween," Lili said. "I think I'm going to do it with my boyfriend, Cole. I don't want to spoil it if it's not going to happen, but it's a TV duo."
