The screen star, who is active on Instagram, has not indicated that he is in a relationship. He could, of course, just be keeping his personal life private. He is very good friends with his on-screen pal Millie Bobby Brown as she is a frequent fixture on his feed.

Ahead of the release of Enola Holmes, Millie and Louis answered 17 questions for Seventeen. Louis admitted that he had been heartbroken before.

"You've been heartbroken, Louis?" Millie asked her co-star.

"Yeah," he shared. 

The actor didn't elaborate any further, so it's unclear who his ex is, or who broke his heart. 

Enola Holmes is available to stream on Netflix now.
