Former Metro Station singer Trace Cyrus has unleashed a vicious verbal attack on the High School Musical star, who is friends with his famous sibling.
Cyrus accuses Tisdale of spreading lies about him throughout Hollywood and calls her the "worst" star he's ever had the misfortune to meet.
In a series of posts on his Twitter.com page, the 21 year old writes: "I've met and know a bunch of celebrities. By far the worst person I've met in my life is Ashley Tisdale."I've never had someone who doesn't know me AT ALL make up so many rumours and bulls**t about me. You don't even know me b**ch... Everyone has an opinion. Everyone's opinion is always right. To them."
