"I'm the luckiest. 🍀✨😘," Bosworth commented on the post.

Last week, the Accepted actor opened up about his relationship — his first time directly naming Bosworth as his partner — on an episode of the Dear Chelsea podcast episode, saying that being "in love" is "such a wonderful feeling."

"Am I allowed to say her name?" host Chelsea Handler, asked Long before he agreed, and she identified the actress as his special someone.

"There's something about it, for me, that I feel like I need to protect and keep sacred because it feels sacred," the Dodgeball star said of keeping the love out of the limelight.

"I've never had anything like this before; I've never experienced this," he added. "So it's something I want to protect and keep, you know?"
