The 28-year-old actor stars in the upcoming romantic comedy, The Perfect Match, and opened up about what he looks for in his own "perfect match."
"Honestly, I like someone who is really grounded, super sweet, honest," Smart said with a smile. "I need them to have a sense of humor. I need them to laugh at what's funny, I need them to get jokes and be funny and be witty and sarcastic."
The actor and dancer, who admits he's "secretly" a romantic at heart, says that Lopez checks all the right boxes for him. The two have even goofed off together in hilarious Dubsmash videos on Smart's Instagram account.
Smart says he "for sure" brings out Lopez's goofy side and that his girlfriend "of course" does the same for him.
"I mean, I'm already goofy -- it doesn't take much," he joked. "We have fun. She's funny."
