16 CANDLES

Talk about a super sweet 16! A tiara-wearing Miley Cyrus has an early b-day party (her big day is Nov. 23) during a visit Monday to The Ellen DeGeneres Show. The Hannah Montana star told the talk-show host about boyfriend Justin Gaston, "He's a singer, he's really cute, and he's nice and he's a Christian and I really like that." The episode airs Nov. 20.
