Former Disney Channel star Ashley Tisdale was being terrorized on Twitter by a crazed fan, according to a report. The Suite Life of Zack & Cody star was sent over 18,000 creepy tweets by a single user and police are investigating.

According to TMZ, the Twitter user, who is believed to be a man, has sent her 18,888 tweets since November 2012. He writes as if they are already in a relationship and sounds delusional.

“My body is yours & even as friends I f***in love how I make u feel like mom maybe we both got issues cuz nobody's perfect,” he wrote in one. Another reads, “I'll never lose u baby even in 20 years til infinity you'll always b my best friend” and “Let it all out on me u can have my heart put a lock on it throw away the key & my soul is yours to keep.”

The person allegedly did approach Tisdale’s house, but didn’t make any physical contact with the 27-year-old actress.

Perez Hilton notes that the suspect was identified and he is being investigated to see if he is still a threat to her.

Tisdale recently starred in Scary Movie V and appeared in the ABC pilot Super Fun Night, which will air in the fall.

Her rep has not commented on the reports.
