Model Chrissy Teigen says she has a crush on actor Zac Efron.

Teigen, who has 17-month-old daughter Luna with her husband and musician John Legend, has admitted to having a "professional" but not "physical" crush on Efron, reports femalefirst.co.uk.

"It's not really like a physical crush on him... like, I really enjoy his films. I enjoy him in a professional manner," Teigen told InStyle magazine.

Teigen says even Legend knows about this.

"John thinks I really like Zac Efron because I can never stop watching his movies," she added.
