Lucy Hale knows first hand how Hollywood is on relationships — which is why she’s keeping mum on her current beau, The Cab‘s Alex Marshall.

The 21-year-old actress shared with Teen Vogue, “I don’t talk too much about him because, well, it’s private. I’ve learned from my past relationships.”

“I’d wrap myself up in my significant other’s life and want to make his world my world. It wasn’t healthy,” Lucy adds about her past relationships.

Lucy previously dated David Henrie.
