Miley Cyrus to be a virginal bride

Miley Cyrus won't have sex until she gets married.

The 16-year-old star - who has been dating underwear model Justin Gaston, 20, for seven months - has vowed to hold onto her virginity until her wedding night because of her strict religious upbringing.

She said: "I want to keep my virginity until I marry. I was brought up in a Christian family."

The 'Hannah Montana: The Movie' actress - who previously dated Jonas Brothers star Nick Jonas, 16 - confessed she finds it difficult to know who she can trust since moving to Los Angeles.

She added to Britain's Daily Mail newspaper: "It's harder finding people who are real - you don't know what's real and what's fake in this city because almost everyone has a motive and everyone wants to get something."

Although she is wary about the motives of others, the young beauty - whose father is 'Achy Breaky Heart' singer Billy Ray Cyrus - is certain she will mistakes over the next few years.

She said: "It's hard growing up in the spotlight, and I'm changing. I can't be the 12-year-old who just moved to Los Angeles for ever. I'm having a great time doing what I do, but I'm also going to stumble and fall. Having my parents close helps."

Last year, the starlet sparked outrage when she posed semi-naked for America's Vanity Fair magazine.

She quickly condemned the images after publication and publicly apologised to her fans.
