Reports suggested the young stars had separated after two years together, prompting both to mock the gossip on social media - but neither Lily nor Cole confirmed they were still together.
Now, in a new interview with Coveteur, Lili has made it clear she and Sprouse are still an item, while talking about the pair's Halloween plans.
"I think I'm leaning in towards a character for Halloween," she 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."
At Variety's Power of Young Hollywood event in Los Angeles last month (August 2019), Cole was asked by Entertainment Tonight how annoyed he was about the split rumours.
"Incredibly," the screen star laughed, before adding, "No, I don't care. That's the nature of our industry. I think you have to poke fun of it a little bit. It's kind of something you sign up for, but as long as can keep it light and fun, it's all good."
