Teen sensation Miley Cyrus has confirmed she's dating touring partner NICK JONAS, the youngest of sibling trio THE JONAS BROTHERS. The Hannah Montana star reveals the couple has been dating since the start of their current sold-out U.S. tour - and her protective father, Billy Ray, approves of the teen romance. She says, "He trusts me, I'm responsible." And the 15-year-old singer/actress insists the romance with Jonas - who is also aged 15 - is limited to rare movie dates. She adds, "What else is there to do?"
