Singer/actress Demi Lovato arrives on the red carpet as the Disney Channel hosts the World Premiere of 'Camp Rock 2: The Final Jam'. Mickey and Minnie Mouse took part in the red carpet festivities, which were held at Alice Tully Hall in Lincoln Center, NYC.

Demi Lovato has revealed she once saw a ghost in her closet.

The Disney star said she was 'scared to death' when she had the creepy encounter as a child.

The 18-year-old told TMZ: 'I've seen a ghost before. It was creepy. It was in my closet when I was about eight and it scared me to death. It just popped out and it was horrible!'

Lovato recently completed a spell in rehab to deal with 'emotional and physical issues' but is now back at work.
