Actor Stephen Baldwin is living a father’s worst nightmare: His baby girl is dating pop bad boy Justin Bieber!

Leggy model Hailey Baldwin, 19, infuriated her dad when she smooched up a storm with the Biebs, 21, on a steamy holiday getaway, sources said.

Now her protective papa plans to let the “What Do You Mean” singer know just what he means!

“Stephen’s going to lay down some rules, man-to-man, concerning his daughter,” a source told The National ENQUIRER.

“And if Justin’s serious about Hailey, he’ll respect her father’s wishes!”

Ironically, “The Usual Suspects” star Stephen — whose big brother is actor Alec Baldwin — introduced Hailey to Justin in 2009.

Last July, Justin boasted about their friendship, posting an Instagram shot with Stephen and writing, “Coolest Baldwin I Know.”

But the singer might change his mind after posting a picture on Instagram of himself locking lips with Hailey for a New Year’s kiss in St. Barts.

“Stephen saw red over the photo Justin dared post of him sucking face with Hailey!” divulged the source. “No father wants to see that!”

Stephen’s also worried about Justin’s scrapes with the law, hair-trigger temper, hard-partying friends and notorious on/off romance with Selena Gomez, said sources.

“Stephen sees lots of promises broken by Justin, and he doesn’t want Hailey to get hurt,” noted the insider.
