Zac Efron is at his "happiest" when he's in a relationship.
The 'We Are Your Friends' actor - who has previously dated Michelle Rodriguez and Vanessa Hudgens - has revealed he is an old romantic at heart and loves nothing more than being in a relationship because he enjoys the "closeness" which comes from sharing his life with a woman.
He said: "I know that I'm happiest when I'm in a relationship and can enjoy the kind of closeness you find when you really care about someone and you know they care about you."
The 27-year-old hunk has been dating model Sami Miró, also 27, for the past year, and said the most important thing in his love life is that his relationships are meaningful because he has always been "very interested" in romance.
He explained to HELLO! magazine: "I never wanted to have superficial relationships. I've always been very interested in romance and everything that comes with that. You have to figure out what you want out of life."
