KJ Apa is giving some major love to his girlfriend.

One month after the Riverdale alum made his red carpet debut with Renée Wilkins, he confirmed they’re in a relationship while sharing insight into their sweet dynamic.

“It’s great,” Apa exclusively told E! News at the world premiere of his new film Jimmy in Dallas, Texas, Nov. 4. “She’s my bestie.”

As for how he knows the model is the one? He put it simply: “Why not?”

The Hate U Give actor is also looking forward to what their relationship could hold in the next chapter.

“I’m all about manifesting,” he added. “I think we manifest everything for ourselves, the positive and the negative. So, you’ve got to be careful about what you spend your time thinking about.”

But the 29-year-old isn’t looking too far into the future, emphasizing to E!, “I try my best to be in the moment.”
