US star Miley Cyrus always finds it "weird and embarrassing" when someone yells "tongue her" during an intimate kissing scene.

The actress-and-singer is engaged to actor Liam Hemsworth and says dating someone in the industry makes such scenes easier as they understand the situation.

Despite being confident, Cyrus admits intimate scenes are never the most comfortable part of making a movie.

She told OK! magazine: “I think it makes it better because they know there really is nothing attached. People have a hard time thinking about it as not being romantic, but it’s really not. Someone comes in and powders you or him and it’s not attractive even though you’re all made up but when you kiss and someone yells: ‘Hold it longer. Use tongue! Tongue her!’...It’s weird and embarrassing. You’re kind of numb to it and it doesn’t bother you anymore.”

Cyrus is starring in 'So Undercover', and plays a private investigator hired to infiltrate a sorority house in College. The movie also stars Kelly Osbourne and Cyrus has revealed why she thinks they get along so well.

She explained: “I like it when people are honest. Like, if I look bad, I want you to tell me if I look bad,” she revealed. I’ve always been that person. I really like honest people and I think that’s why me and Kelly get along so well, and I think a lot of people are put out by it. They can’t believe that she really has no filter, but I don’t really either.”
