The 27-year-old actor says he holds his "Kingsman: The Golden Circle" co-star high in regard, reports FemaleFirst.
"I seek his company outside of work, I think the world of him, I text him and ask how he's doing," Egerton tells Shortlist magazine.
When asked if the Oscar-winning star replies to his messages, the actor says it depends on if he has his phone nearby.
"I suppose it depends if his phone's next to him. Or it'd take longer if he's doing his tie," he said.
